DC12V 60W Desktop Power Supply
1.0 General
The specification defines the performance characteristics of a 60W
Continual, Single Output level switching power supply for +12V,5000mA max .
The power supply has designed highly reliable and meet international safety
and radiation requirements.
2.0 Input Requirements
2.1 Input Voltage:100~240Vac
2.2 Rated Input Frequency:50/60Hz
2.3 Maximum Input Power:60W
2.4 Input Current :1240mA rms max AC 90V input and DC output full load
2.5 Input Protection
The power supply shall be protected against power line surges and any
abnormal condition by 2A/250VAC fuse
2.6 AC Inrush Current
Peak inrush current shall be limited to 60 A 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. Theconformance test for this
requirement shall be performed at the rated input voltage.Voltage and
current waveforms will be observed on an oscilloscope followingclosure 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.
2.7 Efficiency
80% min. At AC nominal input @ output full load
2.8 Power Consumption
0.3W rms max At AC maximum input @ output min load
3.0 Output Requirements
3.1 Turn On Delay
2000 mS At nominal input AC voltage and full load
Test on delay is measured from 0 voltage output to the main output
regulation.
3.2 Rise Time
The Supply shall have a start-up rise time of less than 20 mS to rise to
within regulation limits for all DC outputs.
3.3 Rating Output Voltage
+12VDC
3.4 Rating Load Current
5000mA
3.5 Rating Output Power
60W
3.6 Line Regulation
The line regulation is less than ±5% while measuring at rated load and
+/-5% of input voltage changing.
3.7 Load Regulation
The load regulation for +12.0V is less than +/-5%, at measured output
load from 10% to 100% rated load .(11.4V-12.6V)
