General Description
The new PMT series of panel mount power supplies is the latest offering from one of the world’s largest power supply manufacturers and
solution providers - Delta. PMT-36V350W1A☐ offers a nominal output voltage of 36 V with a wide operating temperature range from 10°C to +70°C and can withstand shock and vibration (in accordance to IEC 60068-2-27 and IEC 60068-2-6 respectively). In addition to
features like overvoltage and overload protections, Delta’s PMT series of panel mount power supplies is unlike many other brands in the
same price level. The PMT series is designed for cost competitive markets without compromising the quality of the components and
product specifications. The series of products has an expected life time of 10 years and will have no output power de-rating from 100 Vac
to 132 Vac & 200 Vac to 264 Vac.

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 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 of ≥ 20 mm (0.79 inch) 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 can be very hot!

•
•
•
Must select correct AC input voltage before turning on (Refer to the “Device Description” on Page 5).
If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further
information.
The device is not recommended to be placed on low thermal conductive surface. For example, plastics.
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.
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 power supply must be mounted by metal screws onto a
grounded metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded metal
surface.

Functions
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.
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Inrush Current
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.
11
Dynamic Response
The power supply output voltage will remain within ±5 of its steady
state value, when subjected to a dynamic load from 10 to 50% and
50 to 100% of its rated current.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.

Overload & Overcurrent Protections (Auto-Recovery)
Overvoltage Protection (Latch Mode)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds
105%~150% of rated load current. 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.
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.
The power supply should be latch
Over Temperature Protection (Auto-Recovery)
It is not recommended to prolong the duration of IO when it is
105%~150%, 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.
12
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.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.

Operating Mode
Redundancy 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 24 V supplies.
Follow simple steps given below to set them up for the
redundant operation:
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, individually connect each power
supply to 50% of rated load at any line voltage from 85-264 Vac,
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 20 A) module shown
on the right of above diagram.
Fig. 5
Redundant Operation Connection Diagram
Step 3.
Connect the system load to Vout. Please note that output voltage 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
25 mV 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.
