Fix connection wiring to the power supply
Two receptacles for the bundled attachment of the
connection wiring are integrated in the left and right housing
panel. Use cable binders to secure the connection wiring
(optional WT-HF 3,6X140 - Item No. 3240744).
Proceed as follows to secure the connection wiring:
– Wire the power supply with sufficient connection
reserve (input terminal blocks, output terminal blocks,
signal terminal block)
– Bundle and set up the connection wiring so that the
ventilation slits on the top and bottom of the housing are
covered as little as possible.
– Thread the cable binders into the necessary
receptacles for the cable binders.

Device connection terminal blocks
The AC input and DC output terminal blocks on the front of
the power supply feature screw connection technology.
For the necessary connection parameters for the
connection terminal blocks, refer to the technical
data section.
9.1
Input
The power supply is operated on single-phase AC systems
or two outer conductors of three-phase systems. The power
supply is connected on the primary side via the INPUT L/N
connection terminal blocks.
9.2
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.
Protection for AC supply
Figure 14
Input AC 100...240 V
The power supply is approved for connection to
TN, TT, and IT power grids with a maximum
phase-to-phase voltage of 240 V AC.

9.3
Output
By default, the power supply is pre-set to a nominal output
voltage of 24 V DC.
The output voltage is adjusted using the potentiometer.
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.

Output characteristic curves
11
The U/I output characteristic curve is optimized for the
following applications:
– 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.
UOut [V]
Figure 16
U/I output characteristic curve
Boost currents
The power supply provides the static boost (IStat. Boost) for a
sustained load supply or the time-limited dynamic boost
(IDyn. Boost).
11.1
Static Boost
For system expansion purposes, the sustained static boost
(IStat. Boost) supports the load supply with up to 125 % of the
nominal current of the power supply. The static boost is
available at an ambient temperature of up to 40 °C.

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.

Two LEDs and a floating signal contact are available for
signaling and function monitoring of the power supply. Use
the rotary selector to select the required functional
monitoring. The available options are monitoring of the
output voltage (DC OK) or alerting when the output power
threshold (POut > PThr) is exceeded.

Rotary selector switch in position DC OK:
In this switch position, the output voltage (UOut) is
monitored. If the DC OK threshold is exceeded
(UOut > 0.9 x USet), the green DC OK LED lights up.
Additionally, the signal output (SIG) is switched to "closed."
If the output voltage drops below the DC OK threshold value
(UOut 50 %, >75 %
or boost >100 %:
In each of these switch positions the output power (POut) is
monitored. When the defined threshold is exceeded, the
yellow LED (POut > PThr) lights up and the signal output
(SIG) "opens."

Operating modes
13.2
Depending on the intended use, the power supply can be
run in series or parallel operation.
13.1
Series operation
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 24 V DC
power supplies are connected in series, an output voltage of
48 V DC is available to supply the loads.

You can connect several power supplies in parallel in order
to increase the power or to supply the loads redundantly.

Parallel operation
Σ = IN
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 or decoupling modules)

13.2.1 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 2.5 A power supplies supply a load with a
nominal current of 2.5 A, for example. During normal
operation of the power supplies, each power supply
therefore supplies 1.25 A.
Always use cables with the same cross sections and lengths
when wiring the power supplies on the DC output side.
A redundancy module can be used to 100% decouple two
power supplies from one another and to ensure the supply.
A distinction is made here between passive and active
redundancy modules. Optimum decoupling with
simultaneous monitoring and minimal power dissipation can
be achieved with the UNO DIODE redundancy module.

13.2.2 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 or
decoupling module such as UNO DIODE or
STEP DIODE.

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.
The following conditions must be met for 1+1 and n+1
redundancy operation of the power supplies in conjunction
with a UNO DIODE redundancy module.
Only use power supplies with the same performance class
and configuration for parallel connection.
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
14.2
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.
14.1
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.

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.

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.
