TECHNICAL DATASHEET
PMT Panel Mount Power Supply
5 V 50 W 1 Phase / PMT-5V50W1A□
Overload & Overcurrent Protections
The power supply's Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 105% of
I (Max load). In such occurrence, the V
O
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 I
the specifications.
It is not recommended to prolong the duration of Io when it is
<105% but >100%, since it may cause damage to the PSU.
Short Circuit Protection
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.

Overvoltage Protection
The power supply's overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed

Over Temperature Protection
As mentioned above, 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.
