2) The Front-End is provided with a typical hysteresis of 5 V during turn-on and turn-off within the ranges.

NOTE: Do not repeat plug-in / out operations below 5sec interval time at maximum input, high temperature condition, or else the

internal in-rush current limiting device PTC may not sufficiently cool down and self over temperature protection may result.

4.1 INPUT FUSE

Quick-acting 16 A input fuses (5.4 × 22.5 in mm) in series with the L-line inside the power supply protect against severe defects.

The fuses are not accessible from the outside and are therefore not serviceable parts.

4.2 INRUSH CURRENT

The AC-DC power supply exhibits an X-capacitance of only 3.88

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 a PTC which will limit the inrush current.
