Over Temperature Protection (OTP)

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.

Table 3.3 Switch Settings for Over Temperature Recovery Options

Switch SW1-8	OTP Shutdown Selection	Description
OFF (OPEN)	Auto Reset (Default)	The supply recovers to normal operation
		when the over temperature condition no
		longer exists.
ON (CLOSED)	Latch OFF	After an over temperature shutdown, the
		supply stays off until you turn the AC
		power switch OFF, then you turn the
		power supply ON to continue use.
