The fuse and a VDR form together with the input filter an effective protection against high input transients. INRUSH CURRENT The AC-DC power supply exhibits an X-capacitance of only 1.47 μF, resulting in a low and short peak current, when the supply is connected to the mains. The internal bulk capacitor will be charged through an power resistor which will limit the inrush current (see Figure 2 and 3). Figure 2: Inrush current, Vin = 115Vac, 90° CH2: Vin (250V/div), CH3: Iin (10A/div) 1 The power supply is provided with a minimum hysteresis of 8 V during turn-on and turn-off within the ranges. |
