Switching Power Supplies

Place of Origin:	Fujian

1) Input specifications:
a) Input voltage: 110-230V AC 5%(90V AC-264V AC)
b) Input frequency: 50 / 60Hz 10%(45Hz-66Hz)
c) Fuse: A frse is included in the AC line circuit. The fuse rating
is as to prevent hazard in the event of an intemal failure of
the power supply.
d) Inrush current: <20A/ms.
e) Earth leakage current: the earth leakage current does not exceed
0.25mA at 264V AC 66Hz input and the Min load condition.
f) Efficiency: 75%min, at 220V AC input full load test

2) Output specifications:
a) Output voltage:
Output1 +3.30v / 100-2000mA/+3.14V-3.46V(voltage limit)/5%tolerance
Output2 +5.00/0-1000mA/+4.75-5.25(voltage limit)/5%tolerance
Output3 +12.0/20-500mA/+11.4-12.6(voltage limit)/5%tolerance
Output4 +24.0/20-100mA/+21.6-26.4(voltage limit)/7%tolerance
Output5 +30.0/0-100mA/+27.0-33.0(voltage limit)/5%tolerance

b) Output ripple:
Measurement of ripple includes a 0.1uF ceramic capacitor and a 47uF
electrolytic capacitor at the output of measuring oscilloscope.
Line ripple: measured with an oscilloscope with a bandwidth of 100 MHZ
Switching ripple: measured with an oscilloscope with a bandwidth of 100MHZ
