5.1 Input Fuse

Double fusing with 5 A slow-blow type (5 × 20 mm), in series with Live and neutral line inside of the power supply protects against severe defects. The fuses and a VDR form to gether with the input filter an effective protectio n against high input transients.

5.2 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 capaci tor will be charged through a power resistor which will limit the inrush current (see Figure 2 and 3). Figure 2: Inrush current, V in = 115 VAC, Phase=90°, CH1: V in (200 V/div), CH2: I in (10 A/div) Test data: the inrush current is 13 A at 115 VAC input Figure 3: Inrush current, V in = 230 VAC, Phase=90°, CH1: V in (200 V/div), CH2: I in (10 A/div) Test data: the inrush current is 30 A at 230 VAC input

5.3 Input Under-voltage

If the sinusoidal input voltage stays below the inp ut 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.

5.4 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 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 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 diode are used as rectifiers for MBC250-1024G and MBC250-1048G separately due to the high output voltage level Figure 4: Efficiency vs. Output Power at 230 VAC, MBC250-1012G Figure 5: Efficiency vs. Output Power at 230 VAC, MBC250-1024G Figure 6: Efficiency vs. Output Power at 230 VAC, MBC250-1048G 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(%) 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(%)

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 linearly to 50% from 50 °C to 70 ºC (ambient temperature at inlet, Fig. 17). Figure 17: Output Current Limitation Curve 100 120 -10 0 10 20 30 40 50 60 70 Ambient Temperature(°C) Io (%)

8 Power Good Signal

The Out-OK output gives a status indication of the converter and the output voltages. It can be used f or control functions such as data protection, central system monitoring or as a part of a self-testing system. Connect the Out-OK (Power Good) as shown in Figure 18, VOK <1.0 V indicates that the output voltage(s) of the converter are within the range. The Out-OK is an active low signal, i.e. Power Good will pull low internally when output is within reg ulation. Out-OK is high impedance internally when there is error condition such as output voltage out of range due to overload or an external overvoltage. This signal is electrically isolated from the output. Figure 18: Power Good signal Power Good Signal Description: 1. O/P V OK – Signal Low, Opto conducting, (max sink current 0.5mA) 2. O/P V Bad – Signal High, Opto opening, (max leakage current 25 μA)
