Remote Sense for type A out 1 The SENSE 1 is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load’s terminals). For output voltage above 8V, the use of remote sense has a max limit of 0.25V voltage dropout between converter’s output and load terminals. For output voltage below 8V, the use of remote sense has a max limit of 0.5V voltage dropout between converter’s output and load terminals. When not used connect SENSE 1 to OUT 1 and SENSE 1 RTN to OUT 1 RTN. Ripple Less than 50 mVp-p, typical (max. 1% of output voltage) Isolation Output to Case: 100 VDC Current Limit & Overload Continuous protection for unlimited time Overload/short-circuit *If output current is higher than 1.5A and there is short due to failure, when the failure is removed the load will be 50%. Efficiency Up to 80%, depending on output voltage. Overvoltage Protection Passive transorb, chosen at 120% ± 10% of nominal voltage. Over Temp. Protection Shutdown if base plate temperature rises above +105 C 5 C. Auto recovery when baseplate cools down to +95 C 5 C.

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 17) SIGNAL RTN INHIBIT and SYNC signals are referenced to this pin. This pin is referenced to IN RTN (pins 7, 8, 22 and 23).
