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 5 V 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 two
different connector options (Terminal Block and Front Face) 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 20 mm 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.

Assembly & Installation
ⒶMounting holes for power supply (device). The power supply shall be mounted on minimum 2 mounting holes using M3 screw
minimum 5 mm length.
ⒷThis surface belongs to customer’s end system or panel where the power supply is mounted.

Fig. 2 Recommended Mounting Orientations
•PM☐-5V50W1AA / PM☐-5V50W1AG: Use flexible cable (stranded or solid) of AWG No. 14-12. User should calculate and select
the suitable wire specification (type/quantity/diameter) according to actual output current. The torque at the Connector shall not
exceed 13 Kgf.cm. The insulation stripping length should not exceed 0.275” or 7 mm (Refer to Fig. 3).
Fig. 3 Assembly Reference
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 Distance
D1 = 4.0 mm Min.

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.
