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-4V350W1A☐ offers a nominal output voltage of 4.2V with a wide operating temperature range
from -20°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 & 180Vac to 264Vac.

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 >70
°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.
To ensure sufficient convection cooling,
always maintain a distance of ≥ 20mm from
fan ventilated surfaces while the device is in
operation.
4.
Depending on the surrounding air
temperature and output load delivered by the
power supply, the device housing can be
very hot!
5. If the device has to be mounted in any other
orientation, please do not hesitate to contact
[email protected] 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 length (Refer to Fig. 4 on the
next page). 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 length (Refer to Fig. 4 on the
next page).
ⒸConnector
ⒹThis surface belongs to customer’s end system or panel where the power supply is mounted.

Fig. 2 Mounting Orientations
– Use flexible cable (stranded or solid) of AWG No. 14-12. 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. 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.
Fig. 4 Assembly Reference
Fig. 3 Mounting Hole Locations and the Safety Distance
Ensure the mounted device is kept at ≥ 4mm safety distance at all sides from other components and equipments. In addition, to ensure
sufficient convection cooling, always maintain a distance of ≥ 20mm 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.
Safety Distance
D1 = 4mm Min.
D2 = 20mm Min.
Only use M4 screw ≤ 5 mm 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 through the base mounting holes at Ⓑ.
This is to keep a safe distance between the screw and internal

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 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.
