2 OVERVIEW
The MBC250-10XXG is a high efficiency and high power
density AC to DC power supply. It use single phase
transition mode PFC converter and well proven two-FET
forward converter with output diode rectifiers, providing
increased system reliability and high efficiency. With
around 1 m/s system air cooling, MBC250-1012G can
delivery up to 228W continuous output power and 252W for
MBC250-1024G and MBC250-1048G .

INPUT FUSE
Double fusing with 5A 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 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.

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

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.

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 ).

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 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.
