Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
If the output capacity is not reduced when the
surrounding air temperature exceeds its
specification as defined on Page 3 under
“Environment”, the device may run into Over
Temperature Protection. When activated, the
output voltage will go into latch mode and
recover when AC power recycles.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance as recommended in the
safety instructions while the device is in
operation.
Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
If the device has to be mounted in any other
orientation, please contact info@deltapsu.com
for more details.

Safety Instructions
•
•
•
•
•
•
ALWAYS switch mains of input power OFF before connecting and disconnecting the input
voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage.
To guarantee sufficient convection cooling, keep a distance of 50 mm (1.97 inch)
above and below the device as well as a lateral distance of 25 mm (0.98 inch) to other
units.
Note that the enclosure of the device can become very hot depending on the surrounding air
temperature and load of the power supply. Risk of burns!
DO NOT insert any objects into the unit.
Hazardous voltages may be present for up to 5 minutes after the input mains voltage is
disconnected. Do not touch the unit during this time.
The power supplies are built in units and must be installed in a cabinet or room (condensation
free environment and indoor location) that is relatively free of conductive contaminants.
Functions
Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Start-up Time
The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied
Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state set value.
Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.

Inrush Current
Dynamic Response
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak value
decreases exponentially during subsequent cycles of AC voltage.
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 10% to
100% of its rated current.
50% duty cycle / 5 Hz to 100 Hz
External Input Protection Device
The unit is protected with internal fuse (not replaceable) at L pin and it has been tested and approved on 20 A (UL) and 16 A (IEC) branch
circuits without additional protection device. An external protection device is only required if the supplying branch has an ampacity greater
than above. Thus, if an external protective device is necessary, or, utilized, a minimum value of 8 A B- or 4A C- characteristic breaker
should be used.

Overload & Overcurrent Protections (Auto-Recovery)
Overvoltage Protection (Latch Mode)
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current (IO) exceeds its
specification as defined on Page 3 under “Protections”. In such
occurrence, once the power supply has reached its maximum
power limit, the protection is activated and the power supply will go
into “Hiccup mode” (Auto-Recovery). The power supply will recover
once the fault condition of the OLP and OCP is removed and IO is
back within the specifications.
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 3 under “Protections”. Power
supply will latch, and require removal/re-application of input AC
voltage in order to restart.
Over Temperature Protection (Latch Mode)
It is not recommended to prolong the duration of IO when it is less
than OLP/OCP point, but greater than 100%, since it may cause
damage to the PSU.
Short Circuit Protection (Auto-Recovery)
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied, the
output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power supply
will return to normal operation after the short circuit is removed.
10
As described in load de-rating section, the power supply also has
Over Temperature Protection (OTP). In the event of a higher
operating temperature at 100% load; or, when the operating
temperature is beyond what is recommended in the de-rating
graph, the OTP circuit will be activated. When activated, power
supply will latch, until the surrounding air temperature drops to its
normal operating temperature or the load is reduced as
recommended in the de-rating graph. Removal/re-application of
input AC voltage will then be required in order to restart.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.

Step 1.
The input voltage applied from Line to Neutral is below the maximum rated input. The input voltage shall be below 240 Vac +10%.
Step 2.
The external protector is needed on N (Neutral) input line to secure a safety. N line does not have internal fuse protection. An appropriate
fuse or circuit breaker should be connected in series with N input line connection like the following.

PFC – Norm EN 61000-3-2
Line Current Harmonic content
Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to
this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects
such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is
important to know whether it is mandatory to meet this standard for a specific application.
