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 > 50°C, the device
may run into Over Temperature Protection.
When activated, the output voltage will go into
bouncing mode and will recover when the
surrounding air temperature is lowered or the
load is reduced as far as necessary to keep the
device in working condition.
If the device has to be mounted in any other
orientation, please do not hesitate to contact
info@deltapsu.com for more details.
In order for the device to function in the manner
intended, it is also necessary to keep a safety
distance of 20mm with adjacent units while the
device is in operation.
Depending on the surrounding air temperature
and output load delivered by the power supply,
the device housing can be very hot!

Safety Instructions
•
•
•
•
•
•
To ensure sufficient convection cooling, always maintain a safety distance of > 20mm from all ventilated surfaces while the
device is in operation.
The device is not recommended to be placed on low thermal conductive surface, for example, plastics.
Note that the enclosure of the device can become very hot depending on the ambient temperature and load of the power
supply. Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning!
Do not touch the terminals while power is being supplied. Risk of electric shock.
Prevent any foreign metal, particles or conductors to enter the device through the openings during installation. It can cause: - Electric shock; Safety Hazard; Fire; Product failure
Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device,
remove L and N connections before removing the Earth connection.
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 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 set value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 95% of its set value, after the input voltage is removed.

Inrush Current
Overload & Overcurrent Protections
Inrush Current is the first surge current seen on the input side
when AC input is applied to the power supply. It is the first pulse
captured; see a typical picture for the inrush current as seen in
the power supply.
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current exceeds 120%
of IO (Max load). In such occurrence, the VO will start to droop and
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.
Dynamic Response
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 0 to
100% of its rated current.
Additionally, if the IO is < 120% but > 100% for a prolong period of
time (depending on the load), the Over Temperature Protection
(OTP) will be activated due to high temperature on critical
components. The power supply will then go into “Hiccup mode”
until power supply cool down.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). This is activated when the
overload condition persists for an extended duration and the
output current is below the overload trigger point but > 100% load.
In the event of a higher operating condition at 100% load, the
power supply will run into OTP when the surrounding air
temperature is > 75°C. When activated, the output voltage will go
into bouncing mode until the operating surrounding temperature
drops to 50°C or output capacity is reduced as recommended in
the de-rating graph.
Overvoltage Protection
Short Circuit Protection
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”.
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.

Operating Mode
 Redundancy Operation
In order to ensure proper redundancy operation for the
power supply unit (PSU), ensure that the output voltage
difference between the two units is kept at 0.45~0.50V
for 24V supplies. Follow simple steps given below to
verify:
Step 1.
Measure output voltage of PSU 1 and PSU 2. If PSU 1
is the master unit, then VO of PSU 1 must be higher than
PSU 2.
In order to set the output voltage, connect the power
supply to 50% load and set the PSU 1 and PSU 2
output voltage.
Fig. 3
Redundancy / Parallel Operation Connection Diagram
Step 2.
Connect the right DRR module, 20A as per the system
requirement to the power supply units PSU 1 and PSU 2
at Vin 1 & Vin 2 respectively.
Step 3.
Connect the system load from Vout. Please note that
output voltage Vout from DRR module will be = VO
(output voltage of power supply) – Vdrop* (in DRR
module).
 Parallel Operation
These DRR modules can also be used for Parallel function in order to increase the output power by N+1 (e.g. 2.5A + 2.5A = 5A or 2.5A
+ 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the PMC-24V075W1AA
is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as
below (Refer to Fig. 3 for the Connection Diagram).
Step 1.
Set output load condition for both supplies at 50% and measure
the output voltages.
Step 2.
Adjust output voltages to the same level or within ±25mV
difference.
Step 3.
Connect PSU 1 and PSU 2 with the DRR-20A module and
measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure
the voltages are within ±25mV.
Step 4.
Output voltage from DRR module Vout will be = VO (output
voltage of power supply) – Vdrop* (in DRR module).
*Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature.

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 form fulfilling this standard, therefore, it is
important to know whether it is mandatory to meet this standard for a specific application.
