2 INPUT REQUIREMENTS
2.1 Input Conditions
The Supply shall operate over the voltage ranges as follows:
Rated Input Voltage
Operating Range
Rated Input Frequency
Rated Input current
Maximum input power
Input current (No Loading)
Power Consumption (No Loading)
200-240Vac
180-264Vac
50/60Hz +/- 3Hz
0.6A Max.
50W
≤15mA
Max. 0.3W
2.2 AC Inrush Current
Peak inrush current shall be limited to 60A for a cold start. Under both
cold & warm start conditions, there shall be no immediate damage or long
term impact on the reliability of the Supply. The conformance test for this
requirement shall be performed at +12.5% of the rated input voltage.
Voltage and current waveforms will be observed on an oscilloscope
following closure of the external power switch. Switch closure will be
repeated until the waveforms show closure coincident with a voltage peak.
The current measured during this occurrence will be defined as the peak
inrush current.
2.3 Brownout and Brownout Recovery
The supply shall be subjected to the following tests while under maximum
rated load No component damage is permitted
2.3.1
BROWNOUT
180 Vac 50 Hz to 0 Vac @ 50 Hz in 1 volt decrements in 30 sec. (Continental Europe.
United Kingdom and Australian
2.3.2 BROWNOUT RECOVERY
0 vac 50 Hz to 180 Vac @ 50 Hz in 1 volt decrements in 30 sec. (continental Europe
United Kingdom and Australian)
After completion of the test, power will be reapplied within the rated line voltage
ranges and normal operation is expected.
