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 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.
