TTL “1” or OPEN – Power supply active (output turned on). TTL “0” or SHORT to SIGNAL RTN – Power supply inhibited (output turned off). If this function is not required, leave this pin unconnected. This signal is referenced to SIGNAL RTN (pin 27) SYNC (pin 28) The SYNC signal is used to synchronize the power suppl y's switching frequency to system's clock. If this function is not required, leave this pin unconnected - the power supply will use its internal clock. External clock frequency can be between 240 kHz to 260 kHz, with duty cycle of 40% to 60%. Valid clock voltage level is between 5 to 12 V. This signal is referenced to SIGNAL RTN (pin 27) SIGNAL RTN (pin 27) Both INHIBIT and SYNC signals are referenced to this pin. This pin is referenced to INPUT RTN (pins 4, 5, 23, 24 and 25).
