1 The current limit is primary side controlled. In the event of a sustained overload condition the thermal protection may cause the unit to
shutdown (restart on cool-down).
2 BW = 20 MHz
3 Measured with a probe according to EN 61204
4 The overvoltage protection is via a primary side second regulation loop, not tracking with Trim control.
