Note
1. Power supply components may degrade, orbe damaged, when the power supply is
continuously used outside the shaded region,refer to the graph shown in Fig. 1& Fig. 2.
2. The PSU will be bouncing and start uptime will not exceed 5s when ambient
temperature at ‐30 °C
3. If the output capacity is not reduced when thesurrounding air temperature >50°C, thedevice will run into Over Temperature
Protection. When activated, power supply will
latch off, until the surrounding air temperature
is lowered or the load is reduced as far asnecessary to keep the device in working
condition, and require removal/re-applicationof input AC voltage in order to restart.
4. In order for the device to function in themanner intended, it is also necessary to keepa safety distance as recommended in thesafety instructions while the device is inoperation.
5. Depending on the surrounding air temperatureand output load delivered by the power
supply, the device can be very hot!

9If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for furtherinformation.
To ensure sufficient convection cooling, always maintain a safety distance of ≥ 50 mm (1.97 inch) from all ventilated surfaces while
the device is in operation.
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 nottouch 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
The power supply must be mounted by metal screws onto a grounded metal surface. It is highly recommended that the Earthterminal on the connector be connected to the grounded surface.

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 ± 10% of its
steady state value, when subjected to a dynamic load from 10% to100%

TECHNICAL DATASHEETPMT2 Panel Mount Power Supply
PMT2 35 W series / PMT-□V35W2B□□Overload & Overcurrent Protections (Auto-Recovery)

Overvoltage Protection (Latch Mode)

The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 110% ofIO (Max load). In such occurrence, the VO will start to droop andonce the power supply has reached its maximum power limit, theprotection is activated and the power supply will go into “Hiccupmode” (Auto-Recovery). The power supply will recover once thefault condition of the OLP and OCP is removed and IO is backwithin 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 under “Protections”. Power supply will
latch, and require removal/re-application of input AC voltage inorder to restart.
The power supply should be latch, and require removal /reapply of input AC voltage in order to restart.

It is not recommended to prolong the duration of Io when it is<110% but >100%, since it may cause damage to the PSU.

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, theoutput current will operate in “Hiccup mode”, as shown in theillustration in the OLP/OCP section on this page. The power supply
will return to normal operation after the short circuit is removed.

Over Temperature Protection (Latch Mode)
As described in Engineering data 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 isrecommended in the de-rating graph. When activated, the output
voltage will go into latch mode until the temperature drops to its
normal operating temperature as recommended in the de-ratinggraph.
