The test voltage should rise and fall in ramp form.
The relevant rise and fall time of the ramp should
be at least two seconds.
6.1
High-voltage dielectric test (dielectric strength
test)
In order to protect the user, power supplies (as electric
components with a direct connection to potentially
hazardous voltages) are subject to more stringent safety
requirements. For this reason, permanent safe electrical
isolation between the hazardous input voltage and the
touch-proof output voltage as safety extra-low voltage
(SELV) must always be ensured.
In order to ensure permanent safe isolation of the AC input
circuit and DC output circuit, high-voltage testing is
performed as part of the safety approval process (type test)
and manufacturing (routine test).
6.2
High-voltage dielectric test during the
manufacturing process
During the manufacturing process for the power supply, a
high-voltage test is performed as part of the dielectric test in
accordance with the specifications of IEC/UL/EN 61010-1.
The high-voltage test is performed with a test voltage of at
least 1.5 kV AC / 2.2 kV DC or higher. Routine
manufacturing tests are inspected regularly by a certification
authority.

QUINT4-PS/3AC/48DC/20
Performing high-voltage testing
If high-voltage testing of the control cabinet or the power
supply as a stand-alone component is planned during final
inspection and testing, the following features must be
observed.
– The power supply wiring must be implemented as
shown in the wiring diagram.
– The maximum permissible test voltages must not be
exceeded.
Avoid unnecessary loading or damage to the power supply
due to excessive test voltages.
For the relevant applicable test voltages and
insulation distances, refer to the corresponding
table (see technical data: electric strength of the
insulation section).
Figure 1
Disconnecting the gas discharge tube
The built-in gas discharge tube inside the device ensures
that the power supply is effectively protected against
asymmetrical disturbance variables (e.g., EN 61000-4-5).
Each surge voltage test represents a very high load for the
power supply. Therefore avoid unnecessary loading or
damage to the power supply due to excessive test voltages.
If necessary, the gas discharge tube inside the device can
be disconnected in order to use higher test voltages.
Following successful completion of testing, please
reconnect the gas-discharge tube.

NOTE: Mechanical damage to the connection
wiring caused by friction
In extreme ambient conditions, e.g., strong
vibrations, protect the connection wiring against
mechanical damage using additional insulation
material. The additional insulation material for
protecting the connection wiring is limited to the
area where the cable binders are attached.
Input
The power supply is operated in a three-phase AC power
grid (star network). The power supply is connected on the
primary side via the INPUT L1/L2/L3/connection terminal
blocks.
The power supply is approved for connection to
TN, TT, and IT power grids (star networks) with a
maximum phase-to-phase voltage of 500 V AC.

Protection of the primary side
Installation of the device must correspond to EN 61010
regulations. It must be possible to switch off the device using
a suitable disconnecting device outside the power supply.
The line protection on the primary side is suitable for this
(see technical data section).
DANGER: Hazardous voltage
An all-pos. fuse must be present for operation on
three-phase and DC systems.

Output
By default, the power supply is pre-set to a nominal output
voltage of 48 V DC.
The output voltage is adjusted via the two arrow keys (-)
and (+) on the front of the power supply.
When you press the arrow key once briefly, the output
voltage is reduced (-) or increased (+) by 3 mV. When you
press the arrow key for longer, the voltage is adjusted in
100 mV increments.
9.4
Protection of the secondary side
The power supply is electronically short-circuit-proof and
no-load-proof. In the event of an error, the output voltage is
limited
If sufficiently long connecting cables are used,
fuse protection does not have to be provided for
each individual load.
If each load is protected separately with its own
protective device, the selective shutdown in the
event of a fault enables the system to remain
operational.
Protection for DC supply
If the power supply is operated with a DC voltage,
the star point of the DC supply system used for
supply must be grounded.
Figure 19
Pin assignment for DC supply voltage
DC applications require upstream installation of a fuse that
is permitted for the operating voltage.

U/I Advanced output characteristic curve
The preset U/I Advanced output characteristic curve is
optimized for the following applications:
– For selective tripping of standard circuit breakers (SFB
technology). The power supply supplies up to 6 times
the nominal current for 15 ms. Loads connected in
parallel continue working.
– When supplying loads with high switch-on currents,
such as motors. The dynamic boost of the power supply
supplies up to 200% of the nominal power for 5 s. This
ensures that sufficient reserve energy is available;
overdimensioning of the power supply is not necessary.
– For system extension. With the static boost, up to
125% of the nominal output power is available for a
sustained period (up to 40°C).
– For fast energy storage charging (e.g., of batteries) to
supply a wide range of loads. The power supply
operates in the nominal operating range. Energy supply
to the load is ensured.
Figure 20
10.2
Smart HICCUP output characteristic curve
The SMART HICCUP output characteristic curve keeps the
thermal load of the connecting cables at a low level in the
event of a sustained overload. If loads are not protected or
are protected in a way that is not permitted, the loads are
supplied for 2 s. The DC output of the power supply is then
switched off for 8 s. This procedure is repeated until the
cause of the overload has been remedied.
The Smart HICCUP output characteristic curve is optimized
for the following applications:
– If only a low short-circuit current is permitted.
– If following an overload or short circuit the output
voltage should be made available again automatically.

restarted via the remote contact. As an option, the power
supply can be switched on by switching the supply voltage
on the primary side off and on.

Configuring the power supply
With the fourth generation of the QUINT POWER power
supply, it is now possible for the first time to adapt the
behavior of the power supply. In addition to setting the
output voltage and selecting the output characteristic
curves, you can configure signal outputs Out 1, Out 2, and
floating signal contact 13/14, for example. Configuration of
the remote input for controlling the power supply or
specification of signal options and signal thresholds also
extend the range of possible applications.
The power supply is configured via the device's internal NFC
(near field communication) interface. This is located behind
the QR code on the front.
11.2
To configure the power supply, proceed as follows:
– Before you can configure the power supply, it should
either be disconnected from the supply voltage or
switched to SLEEP MODE.
– To switch the power supply to SLEEP MODE, use one
of the external circuits. The following connection
versions are possible between the Rem (remote input)
and SGnd (signal ground) connection terminal blocks.
Figure 23
In order to configure the power supply via the NFC interface,
the following hardware and software requirements must be
met:
– PC or notebook (as of Windows 7, Microsoft.Net
Framework 4.5, USB 2.0 interface, 50 MB hard disk
capacity, QUINT POWER software).
– Programming adapter:
TWN4 MIFARE NFC USB ADAPTER (Order No.
2909681) is plugged into the USB interface.
– Programming software: the QUINT POWER software
has been successfully installed.
–
Hold the USB-PROG-ADAPTER in front of the mounted
power supply such that the NFC antenna symbol is over
the QR code.

Boost currents
The power supply provides the static boost (IStat. Boost) for a
sustained load supply or the time-limited dynamic boost
(IDyn. Boost).
12.1
Static Boost
For system expansion purposes, the sustained static boost
(IStat. Boost) supports the load supply with up to 112% of the
nominal current of the power supply. The static boost is
available at an ambient temperature of up to 40°C.

Ordering a configured power supply
Customer-specified QUINT POWER power supplies are
ordered as a KMAT item (configurable material) and are
configured during the production process in the factory. The
power supply is therefore supplied ready to connect for your
specific application.
You can type in the the web code
phoenixcontact.net/webcode/#0852
to configure and order your power supply.
12.2
Dynamic Boost
Dynamic boost (IDyn. Boost) delivers up to 150 % of the power
supply nominal current to supply high loads. This temporary
power supply to the load lasts a maximum of 5 s at an
ambient temperature of up to 60 °C. The energy supplied
adaptively for the load supply and the recovery time (tPause)
are calculated based on the specific load situation using
algorithms (see recovery time tables).

SFB Technology
13.3
SFB Technology (selective fuse breaking) can be used to
quickly and reliably trip miniature circuit breakers and fuses
connected on the secondary side. In the event of a short
circuit on the secondary side, the power supply supplies up
to 6 times the nominal current for 15 ms. The faulty current
path is switched off selectively.
Loads that are connected in parallel are still supplied with
energy. Operation of these system parts is ensured. In order
to always enable the reliable tripping of circuit breakers and
fuses, certain framework conditions must be observed (see
SFB configuration section).
Observe the following framework conditions for determining
the maximum distance between the power supply and load:
– The performance class of the power supply
– The cross section of the connecting cable
– The tripping characteristic of the fuse component

Tripping circuit breakers
The circuit breaker is tripped by the high SFB current of the
power supply, typically within 3 to 5 ms. As a result, voltage
dips at loads that are connected in parallel are avoided.

Tripping a fuse
Fuses are tripped by melting the predetermined breaking

To double the output voltage, connect two power supplies in
series. Only use power supplies with the same performance
class and configuration for series operation. If two 48 V DC
power supplies are connected in series, an output voltage of
96 V DC is available to supply the loads.

Observe the following points when carrying out parallel
connection:
1. Use power supplies of the same type and performance
class
2. Setting the same output voltages
3. Using the same cable cross sections for wiring
4. Using the same cable lengths for the DC convergence
point
5. Operating power supplies in the same temperature
environment
6. When three or more power supplies are connected in
parallel, each output must be protected (e.g., with
circuit breakers, fuses or decoupling modules)
We recommend the configuration "parallel
operation" for a parallel connection.
For more detailed information on the operating
mode for parallel operation, refer to the user
manual for the QUINT POWER software or the
QUINT POWER app.

15.2.1 Redundancy operation
Redundant circuits are suitable for supplying systems and
system parts which place particularly high demands on
operational reliability.
If energy is to be supplied to the load with 1+1 redundancy,
two power supplies of the same type and performance class
must be used. In the event of an error, it must be ensured
that one of the power supplies is able to provide the total
required power for the load. This means that in redundancy
mode, two 20 A power supplies supply a load with a nominal
current of 20 A, for example. During normal operation of the
power supplies, each power supply therefore supplies 10 A.
15.2.2 Increased power
When n power supplies are connected in parallel, the output
current is increased to n x IN. Parallel connection for
increased power is used when extending existing systems.
If the individual power supply does not cover the current
consumption of the most powerful load, parallel connection
of power supplies is recommended.
When three or more power supplies are
connected in parallel, each output must be
protected separately, e.g., by a circuit breaker,
fuse or decoupling module such as
QUINT ORING, QUINT S-ORING or
QUINT DIODE.
Always use cables with the same cross sections and lengths
when wiring the power supplies on the DC output side.
Redundancy modules can be used to fully decouple two
power supplies from one another and to ensure the supply.
Optimum decoupling can be achieved with the
QUINT DIODE redundancy module.

Certain specifications apply in redundancy operation with
regard to the configuration of the keepout areas. In
redundancy operation, the power supplies are operated with
maximum half the nominal power. The keepout areas are
therefore reduced.
Using the signaling settings, you can monitor whether both
power supplies are being operated with ≤ half the nominal
load. In the case of system extension, an overload is
prevented if one of the power supplies fails.

Derating
16.3
The QUINT POWER power supply runs in nominal
operation without any limitations. For operation outside the
nominal range, the following points should be observed
depending on the type of use.
16.1
Ambient temperature
When operating the power supply at an ambient
temperature of > 60 °C, a power derating of 2.5 %/K should
be observed. Up to an ambient temperature of 40 °C, the
power supply can take power from the static boost for a
sustained period. In the 40 °C to 60 °C temperature range,
the power supply can output more than the nominal power
for a sustained period.
Figure 48
Output power depending on the ambient
temperature
Installation height
The power supply can be operated at an installation height
of up to 2000 m without any limitations. Different data
applies for installation locations above 2000 m due to the
differing air pressure and the reduced convection cooling
associated with this (see technical data section). The data
provided is based on the results of pressure chamber testing
performed by an accredited test laboratory.

Input voltage
The power supply is designed for operation in a three-phase
network. If one phase fails or drops in the event of a fault
(e.g., due to starting a load on the affected phase as in the
case of a cooling unit), sustained operation on two phases is
possible. This type of scenario is already covered for QUINT
POWER by virtue of its approval.

Position-dependent derating
The fanless convection-cooled power supply can be snapped onto all DIN rails according to EN 60715.
The power supply should be mounted horizontally for heat dissipation reasons (AC connection terminal blocks
facing downward). Please observe the derating for any mounting other than the normal mounting position. Reduce
the output power based on the prevailing ambient temperature.
The recommended output power for different mounting positions and ambient temperatures can be found in the
characteristic curves below.
Exceeding these values will reduce the service life of the power supply.
