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. +1.866.513.2839 [email protected] © 2015 Bel Power Solutions, Inc.

Once the input voltage returns within the normal operating range, the supply will return to normal operation again. POWER FACTOR CORRECTION Power factor correction (PFC) is achieved by controlling the input current waveform synchronously with the input voltage. A specified 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.

BCD.00186_AD ABC400 Series The Out-OK output gives a status indication of the converter and the output voltages. It can be used for control functions such as data protection, central system monitoring or as a part of a self-testing system. Connecting the Out-OK as shown in Figure 16, Vok <1.0 V indicates that the output voltage(s) of the converter are within the range. Note: using the potentiometer, the monitor level tracks the programmed output voltage. In an error condition, if the output voltage is out of range due to overload or an external overvoltage, Vok will approach Vp. The output is formed by an NPN transistor. The signal is isolated from the output. Figure 16: Power Good signal Power Good Signal Description: 1. O/P V OK – Signal Low, Opto conducting, (max sink current 0.5 mA) 2.
