Using Over Temperature Protection (OTP)
The OTP circuit protects the power supply in the event of excessive temperature. The
protection circuit monitors the temperature of a supply heatsink using a temperature
sensor, and will activate the internal shutdown circuit whenever the maximum
temperature is exceeded.
The red OTP LED on the front panel lights up when an OTP shutdown occurs.
Resetting the
OTP circuit
To reset the OTP after it activates:
1. The supply recovers to normal operation when the over temperature condition
no longer exists.
OR
1. Turn the AC power switch OFF.
2. Correct the situation causing the over temperature condition.
3. Turn the AC power switch ON.
