INPUT FUSE
A slow-blow 8A input fuses (5 × 20 mm) in series with live line inside the power supply protects against severe defects. 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)

The power supply is provided with a minimum hysteresis of 8 V during turn-on and turn-off within the ranges.

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.
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.

Efficiency (%)
The high efficiency (see Figure 4, 5 and 6) is achieved by using state-of-the-art silicon power devices in conjunction with
interleaved transition mode PFC topology minimizing switching losses. Synchronous rectifiers on the output reduce the losses
in the high current output path for ABC400-1012G schottky diode and ultra-fast diode are used as rectifiers for
ABC400-1024G and ABC400-1048G due to the high output voltage level.

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.
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 15).

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.
