Over Temperature Protection (OTP)
The OTP function allows you to select how the power supply recovers from an over
temperature shutdown using the rear panel switch S1-8. See
settings and selections. The OTP shutdown circuit activates before the internal
components can exceed their safe internal operating temperatures. When an OTP
shutdown occurs, the front panel OTP LED turns on. An Over temperature condition
will disable the output.
