External with Cout = 2×150μF polymer capacitors. 4. It’s necessary to equip the external input capacitors at the input of the module. The capacitors should connect as close as possible to the input terminals that ensuring module stability. The external Cin is 4×47μF ceramic capacitors at least. 5. Case 1 :On/Off input is set to logic low (module on) and then input power is applied (delay from instant at which Vin=Vin(min.) until Vo=10% of Vo(set)) 6. Case 2 :Input power is applied for at least one second and then the On/Off input is set to logic low (delay from instant at which Von/off=0.3V until Vo=10% of Vo(set)) CAUTION： This power module is not internally fused. An input line fuse must always be used. Rev:0 2018/10/31
