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 first range of PMT products will offer a nominal output voltage of 12V 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 will have no output
power de-rating from 90 Vac to 264 Vac. This versatile series has three different connector options (Terminal Block, Front Face and
Harness) and can also be converted into L Frame (PML) or Open Frame (PMB) type of power supplies to satisfy different application
needs.

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.
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.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 20 mm (0.79 inch) with
adjacent units while the device is in operation.
Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
If the device has to be mounted in any other
orientation,

Assembly Reference
Ensure the mounted device is kept at ≥ 4 mm (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 ≥ 20 mm (0.79 inch) from ventilated surfaces while the device is in
operation.
PM☐-12V35W1AA☐ / PM☐-12V35W1AG: Use flexible cable (stranded or solid) of AWG No. 22-12. 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 (11.23 lbf.in). The insulation stripping length should not exceed 0.275” or 7 mm (Refer to Fig. 3).

For PMT and PML Series (Refer to Fig. 4): Only use M3 screw ≤ 6mm
(0.23 inch) 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 (3.47~6.08 lbf.in).
For PMB Series: (Refer to Fig. 3): The mounting holes on any mounting
accessories for the device should be kept at a diameter of < 6.5 mm (0.26
inch). This is to ensure sufficient safety distance between the mounting
screw and the components around the mounting holes on the PCBA.
Therefore, the diameter of the mounting screw should be kept at < 6.5
mm (0.26 inch).

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.

Functions
Start-up Time
The time required for the output voltage to reach 90% of its final steady state 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 final steady state set value.
Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Inrush Current
Dynamic Response
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.
The power supply output voltage will remains within ± 5% of its
steady state value, when subjected to a dynamic load from 0 to
100% of its rated current.

Overload & Overcurrent Protections (Auto-Recovery)
Overvoltage Protection (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 120% of
IO (Max load). In such occurrence, the VO will 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 IO is back within
the specifications.
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 (Auto-Recovery)
It is not recommended to prolong the duration of IO when it is
100%, since it may cause damage to the PSU.
As described in load de-rating section, 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 (Auto-Recovery)
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.
