2002-02-27T223-0060/02Added an alternative construction. The output diode isreplaced by an electronic board with a FET transistor toreduce the power loss and reduce the temperature risewithin the unit (see also list of critical components).
Output voltage range for ML50 version is extended to 1248 V d.c.

60950 , UL60950 , IEC60950 third edition.

1.2.8Circuits and circuit characteristicsThe outputs are SELV, non hazard energy level.

1.7.10IT Power SystemThe Power Supply was tested for IT and TNPower Systems.

2.10Pollution degreeThe equipment was evaluated for use in apollution degree II environment.

4.5Heating testThe following components should be given specialconsiderations during the end-use heating testsbecause of temperatures achieved during thecomponent level testing:ComponentT1 windinginput).

max. Temp. Achieved:87 °C at 24 °C ambient (85 Vdc5.3.6Abnormal testingThe product is tested on a 32 a branch circuit. Ifused on a branch circuit greater than this,additional testing might be necessary.

Annex CWorking voltageThe working voltage present is 335 Vrms, 508 Vpeak. The electrical strength test for the powersupply shall be based on these values.

1.5TerminalsThe terminals are suitable for field wiring.
