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. The PMT products also offer a nominal output voltage of 5V with a wide operating temperature range from -
10°C to +70°C and can withstand shock and vibration requirements (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 this versatile product has three
different connector options (Terminal Block, Front Face and Harness) and can also be converted into L Frame (PML) type of power
supplies to satisfy different application needs.

Engineering Data
De-rating
Output De-rating VS. Input Voltage
Note
1. 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.
2. If the output capacity is not reduced when the
surrounding air temperature >50
°C, 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.
3. 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.
4. Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please do not hesitate to contact
[e-mail] for more details.

Ensure the mounted device is kept at ≥ 4 mm safety distance at all sides from other components and equipments. In addition, to ensure
sufficient convection cooling, always maintain a distance of ≥ 20 mm from ventilated surfaces while the device is in operation.

Safety Instructions
•If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further
information.
•L frame (PML) and Open frame (PMB) options are to be manufactured by Delta and not to be reconfigured by users from the
standard enclosed configuration.
•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.
•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 surface.
•Warning (For Standard Terminal Block and Front Face Terminal Block products): 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.
For PMT and PML Series (Refer to Fig. 4): Only use M3 screw ≤ 3 mm
through the base mounting holes. This is to keep a safe distance between
the screw and internal components. Recommended mounting tightening
torque: 4~7 Kgf.cm.

Functions
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.
■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.
Dynamic Response
The power supply output voltage will remains within ±10% of its
steady state value, when subjected to a dynamic load from 0 to
100% of its rated current.
50% duty cycle / 5 Hz to 1 KHz

Overload & Overcurrent Protections
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 105% of
IO(Max load). In such occurrence, the VOwill 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 IOis back within
the specifications.
It is not recommended to prolong the duration of Io when it is
<105% but >100%, since it may cause damage to the PSU.
Overvoltage 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”.
Over Temperature Protection
As mentioned above, 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
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.
