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)
