File Name: M1981cat Rev D Date: 2017/04/20 Page 4 of 5 Enercon Technologies Ltd 31 Yad Harutsim St., Netanya, Israel Functions and Signals SENSE The SENSE line is used to achieve accurate voltage regulation at load terminals. To use this feature, connect this pin directly to load's positive terminal. If this function is not required, short SENSE pin to OUTPUT pins as close as possible to the unit. SENSE RTN The SENSE RTN line is used to achieve accurate voltage regulation at load terminals. To use this feature, connect this pin directly to load's negative terminal. If this function is not required, short SENSE RTN pin to OUTPUT RTN pins as close as possible to the unit. Note: The use of remote sense has a limit of voltage dropout between the converter's output and the load's terminals of approximately 5% of nominal output voltage. INHIBIT The INHIBIT signal is used to turn the power supply ON and OFF. 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. SYNC The SYNC signal is used to synchronize the power supply's switching frequency to system 's clock. Valid external clock frequency is 250kHz ±10kHz. If this function is not required, leave this pin unconnected - the power supply will use its internal clock. CHASSIS The CHASSIS pin allows additional connection of unit's chassis to system ground.
