The fuses and a VDR form together with the input filter an effective protection against high input transients. 5.1 INRUSH CURRENT The AC-DC power supply exhibits an X-capacitance of only 2.0 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 3: Inrush current, Vin = 230VAC,Phase=90° CH1: Vin (200V/div), CH2: Iin (10A/div) Test data: the inrush current is 30A at 230VAC input. Figure 2: Inrush current, Vin = 115VAC, Phase=90° CH1: Vin (200V/div), CH2: Iin (10A/div) Test data: the inrush current is 13A at 115VAC input. Rev. AA2, 26-Mar-2012 5.2 INPUT UNDER-VOLTAGE If the sinusoidal input voltage stays below the input under voltage lockout threshold Vi on, the supply will be inhibited. Once the input voltage returns within the normal operating range, the supply will return to normal operation again. 5.3 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 single phase transition mode topology giving outstanding PFC Page 4 / 15 www.power-one.com MBC250-10XXG Data Sheet 12VDC, 24 VDC, 48VDC losses. Synchronous rectifiers on the output reduce the losses in the high current output path for MBC250-1012G . 5.4 EFFICIENCY The high efficiency (see Figure 4, 5 and 6) is achieved by using state-of-the-art silicon power devices in conjunction with transition mode PFC topology minimizing switching Schottky diode and ultra fast diode are used as rectifiers for MBC250-1024G and MBC250-1048G separately due to the high output voltage level. 92 89 86 83 80 77 74 71 68 65 Efficiency(%) Efficiency (%) results over a wide input voltage and load ranges.

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 18, 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 18: Power Good signal 9 ELECTROMAGNETIC COMPATIBILITY 9.1 IMMUNITY Note: Most of the immunity requirements are derived from EN 61000-6-1:2007.
