Features Universal AC input / Full range AC input active surge current limiting Built-in active PFC function, PF>0.95 Protections:Short circuit/Over load/Over voltage/Over temperature Built-in constant current limiting circuit Current sharing up to 2 units or 2000W Built-in remote ON-OFF control Built-in remote sense function SpecificationOver Load Protection 115~140% of rate load. Protection type : Constant current limiting, recovers automatically after fau Over voltage protection type : Shunt down o/p voltage, re-power on to recover. Over temperature TSW1: 95?C (Detect on the heatsink of PFC MOSFET) TSW2: 90?C (Detect the winding of output choke) Protection type : Shun down o/p voltage, recovers automatically after temperature goes down Remote control RC+/RC-: 0 ~ 0.8V=power on ; 4 ~ 10V=power off sink current
