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

info@deltapsu.com 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

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.
