Use: Apply short circuit or TTL "LOW" to turn off the power supply. Leave open or apply TTL "HIGH" to turn on the power supply. Referenced to: SIGNAL RTN SYNC Description: Synchronizes internal switching frequency to system clock. Use: Apply TTL level, 250 kHz ± 10 kHz, 50% duty-cycle clock. Leave open if unused. In this case, the switching frequency will be set by the internal clock (250 kHz) Referenced to: SIGNAL RTN SIGNAL RTN Description: Signals return reference. Referenced to: Connected by a 100 Ω resistor to INPUT RTN SENSE Description: Used to achieve accurate voltage regulation at load terminals, to compensate for voltage drop across the leads connecting the converter to the load, 0.25 V ± 0.1 V Use: Connect SENSE line directly to the load's positive terminal, and SENSE RTN directly to the load's negative terminal. If not used, connect SENSE to OUTPUT and SENSE RTN to OUTPUT RTN. Do not leave open! POR (Protection Override) - Optional Description: The POR signal disables the input under voltage lockout, input over voltage lockout, over temperature protection and peak load duration limiter. Please consult factory for details.
