The PMT-24V350W1A☐ offers a nominal output voltage of 24V with a wide operating temperature range from -10°C to +70°C and can
withstand shock and vibration according to IEC 60068-2. 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 100Vac to 132Vac & 200Vac to 264Vac.

•
•
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 and/or 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.

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 remain within ±1000mVpp of
its steady state value, when subjected to a dynamic load from 10
to 50% and 50 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 exceeds >25A
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”.
Over Temperature Protection (Auto-Recovery)
It is not recommended to prolong the duration of IO when it is
14.6A, 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 derating 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 Connection Diagram
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 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 the power supply to 50% of rated load, 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-40N (or 40A) module shown on the right
of above diagram.
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).
*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.
