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 SW1-8. See Table 3.3 for the
switch settings and selections. See "Rear Panel Connectors and Switch" on page 18
for more information about the switch. 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.
