TTL “1”or OPEN – will turn on the power supply (For normal operation leave the signal not connected). TTL “0” – will turn off the power supply. SYNC signal The SYNC signal is used to allow the power supply frequency to sync with the system frequency. The system frequency can be 250 kHz ± 10 kHz. When not connected, the power supply will work at internal frequency, close to 250 kHz ± 10 kHz. SIGNAL RTN The SIGNAL RTN is used as grounding for SYNC and INHIBIT signals. This is referenced to the INPUT RTN pin. SENSE # The SENSE # is used to achieve accurate load regulation at the load terminals. This is done by connecting these pins directly to their respective load terminals. The use of remote sense has a limit of voltage dropout between converter’s output and load terminals of 2-10% of voltage output. When not used connect SENSE # to OUT # and SENSE # RTN to OUT # RTN for each of the outputs. CHASSIS This chassis pin allows connection of the unit chassis to system chassis.
