The fuse and a VDR form together with the input filter an effective protection against high input transients. 5.2 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). 1 The power supply is provided with a minimum hysteresis of 8 V during turn-on and turn-off within the ranges.

Once the input voltage returns within the normal operating range, the supply will return to normal operation again. 5.4 POWER FACTOR CORRECTION Power factor correction (PFC) is achieved by controlling the input current waveform synchronously with the input voltage. A sp ecified PFC controller is implemented in the interleaved transition mode topology giving outstanding PFC results over a wide input voltage and load ranges. The input current will follow the shape of the input voltage. 5.5 EFFICIENCY The high efficiency (see Figure 4, 5 and 6) is achieved by using state-of-the-art silicon power devices in conjunction with interleaved transition mode PFC topology minimizing switching losses. Synchronous rectifiers on the output reduce the losses in the high current output path for ABC400-1012G schottky diode and ultra-fast diode are used as rectifiers for ABC400-1024G and ABC400-1048G due to the high output voltage level. tech.support@psbel.com 5 92.0 90.0 88.0 86.0 84.0 82.0 80.0 78.0 76.0 Series1 0 100 200 300 400 Efficiency (%) Efficiency (%) ABC400 Series 92.0 90.0 88.0 86.0 84.0 82.0 80.0 78.0 76.0 Series1 0 100 200 Po (W) 300 400 Po (W) Efficiency (%) Figure 4: Efficiency vs. Output Power at 230VAC, ABC400-1012G Figure 5: Efficiency vs. Output Power at 230VAC, ABC400-1024G 92.0 90.0 88.0 86.0 84.0 82.0 80.0 78.0 76.0 Series1 0 100 200 300 400 Po (W) Figure 6: Efficiency vs. Output Power at 230VAC, ABC400-1048G 6.
