Over Temperature Protection (OTP)

The over temperature protection circuit shuts down the power supply’s output when
the power supply exceeds internal temperature limits. When an OTP shutdown
occurs, the OTP LED on the front panel turns on. You can select the way that the
power supply recovers from an over temperature shutdown by setting the SW1-8
switch on the rear panel.

Table 3.3

shows the possible switch settings.
