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-48V350W1A☐☐ offers a nominal output voltage of 48V 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 100Vac
to 132Vac & 200Vac to 264Vac.

Engineering Data
Output Load De-rating VS Surrounding Air Temperature
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
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.
3. In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of ≥ 20mm (0.78 inch) with
adjacent units while the device is in operation.
4. Depending on the surrounding air temperature
and output load delivered b
y the power
supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please contact
[email protected]om for more details.

Assembly & Installation
ⒶSide Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 5mm (0.20 inch) length (Refer to Fig.
4). This is to maintain a safety distance between the screw and internal components.
ⒷBase Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 4mm (0.16 inch) length (Refer to Fig.
4).
ⒸConnector
ⒹThis surface belongs to customer’s end system or panel where the power supply is mounted.

Fig. 2 Mounting Orientation
•Use flexible cable (stranded or solid) of AWG No. 22-12. The input/output connectors’ allowable current is 23A max per pin. 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 13Kgf.cm (11.23 lbf.in). The insulation stripping length should not exceed 0.275” or 7mm.
•Recommended mounting torque of the product and its mounting accessories is 9~12Kgf.cm (7.81~10.42 lbf.in).
Fig. 4 Assembly Reference
Only use M4 screw ≤ 5 mm (0.20 inch) through the base mounting holes
at Ⓐ.This is to keep a safe distance between the screw and internal
components.

Only use M4 screw ≤ 4 mm (0.16 inch) through the base mounting holes
at Ⓑ.
Fig. 3 Mounting Hole Locations and the Safety Distance
For safety reasons, please ensure the mounted device is kept at ≥ 4mm (0.16 inch) safety distance at all sides from other components
and equipments. In addition, to ensure sufficient convection cooling, always maintain a distance of ≥ 20mm (0.79 inch) from fan ventilated
surfaces while the device is in operation. Please insert an insulation sheet between the system and product, if the safety distance is <
4mm (0.16 inch).
Safety Distance
D1 = 4mm Min.
D2 = 20mm Min.

Safety Instructions
•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.
