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 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. 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.

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 inp ut 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

Rev. AA2, 26-Mar-2012 Page 5 / 15 www.power-one.com MBC250-10XXG Data Sheet 12VDC, 24 VDC, 48VDC results over a wide input voltage and load ranges. The input current will follow the shape of the input voltage.

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 losses. Synchronous rectifiers on the output reduce the losses in the high current output path for MBC250-1012G . Schottky diode and ultra fast di ode are used as rectifiers for MBC250-1024G and MBC250-1048G separately due to the high output voltage level. 0 50 100 150 200 250 Po(W) Efficiency (%) 65.00 68.00 71.00 74.00 77.00 80.00 83.00 86.00 89.00 92.00 0 50 100 150 200 250 300 Po(W) Efficiency(%) Figure 4: Efficiency vs. Output Power at 230VAC, MBC250-1012G Figure 5: Efficiency vs. Output Power at 230VAC, MBC250-1024G 65.00 68.00 71.00 74.00 77.00 80.00 83.00 86.00 89.00 92.00 0 50 100 150 200 250 300 Po(W) Efficiency(%) Figure 6: Efficiency vs. Output Power at 230VAC, MBC250-1048G

7.1 OVERVOLTAGE PROTECTION

The AC-DC power supply provides a fixed threshold overvoltage (OV) protection implemented with a HW comparator. Once an OV condition has been triggered, the supply will shut down and latch the fault condition. The latch can be unlocked by disconnecting the supply from the AC mains only.

7.2 CURRENT LIMITATION

The main output current limitation will decrease with linear derating to 50% at 70 ºC if the ambient (inlet) temperature increases beyond 50 °C (see Figure 17 ). Figure 17: Output Current Limitation Curve 100 120 -10 0 10 20 30 40 50 60 70 Ambient Temperature(°C) Io (%) Series1

8 POWER GOOD SIGNAL

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 syste m 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
