and a highly dependable minimum hold-up time. The state-of-the-art design is made to withstand harsh industrial environments. What
makes the product stands out from the crowd is its lightweight full aluminum body design, which can withstand shock and vibration
according to IEC 60068-2-6. The PMC series also offers overvoltage and overload protection. Using a wide input voltage range design,
it is compatible worldwide. The input also includes DC operating voltage from 125-375 Vdc. Best of all, this excellent design and quality
does not come with a big price tag.

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
surrounding air temperature exceeds its
specification as defined on Page 3 under
“Environment”,, the device will 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.
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,

To ensure sufficient convection cooling, always maintain a safety distance of ≥ 20 mm (0.79 inch) from all ventilated surfaces while
the device is in operation.
The device is not recommended to be placed on surface with low thermal conductivity, such as plastics, for example.
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 from entering the device through the openings during installation. It may cause:
Electric shock; Safety Hazard; Fire; Product failure
The appliance is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or instruction.
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.
The device is earthed and must be inaccessible.

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 0%
to 100% of its rated current.

Overload & Overcurrent Protections (Auto-Recovery)
Overvoltage Protection (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current (IO) exceeds its
specification as defined on Page 3 under “Protections”. In such
occurrence, the output voltage (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” (AutoRecovery). 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”.
Over Temperature Protection (Auto-Recovery)
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.
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, the power supply will run into
OTP when the operating temperature is beyond what is
recommended in the de-rating graph. When activated, the output
voltage will go into bouncing mode until the temperature drops to
its normal operating temperature as recommended in the de-rating
graph.
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.

Redundant Operation
In order to ensure proper redundant operation for the
power supply units (PSUs), the output voltage difference
between the two units must be kept at 0.45~0.50 V for
these 24V supplies. Follow simple steps given below to set
them up for the redundant operation:

from 85-264Vac, and set the PSU 1 and PSU 2 output
voltage.
Step 2.
Connect the power supply units PSU 1 and PSU 2 to Vin 1
& Vin 2, respectively, of the DRR-20N (or 20A) module
shown on the right of above diagram.
Fig. 3
Redundancy Operation Connection Diagram
ltage Vout from DRR module 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.
Parallel Operation
The power supply units (PSUs) can also be used for
parallel operation in order to increase the output power.
The difference in output voltage between the two units
must be kept to within 25mV of each other. This difference
must be verified with the same output load connected
independently to each unit.
Parameters such as EMI, inrush current, leakage current,
PARD, start up time will be different from those on the
datasheet, when two units are connected in parallel. The
user will need to verify that any differences will still allow
the two power supplies connected in parallel will work
properly in their product/application.
