Switching Power Supplies

Place of Origin:	Fujian

1.Input Characteristics:
a.Input voltage:110-230VAC?15%(90VAC-264VAC)
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
Safety 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 264VAC
66Hz Input and the Min load condition.
f.Efficiency:75%min,at 220VAC input full load test.
2.Output Specification
a.Output voltage:the +16V and +23V outputs are used for LNBP so that either of them
shall be loaded at a time
output1 +3.30v /300-1500mA/+3.14V-3.46V(
voltage limit)/5%tolerance/4.95Watt/
output2 +5.00/50-800mA/+4.75-5.25(
voltage limit)/5%tolerance/4.0Watt
output3 +12.0/0-100mA/+11.4-12.6(
voltage limit)/5%tolerance/1.2Watt
output4 +16.0/0-450mA/+15.0-17.0(
voltage limit)/7%tolerance/7.2Watt
output5 +23.0/0-450mA/+21.8-24.2(
voltage limit)/5%tolerance/10.35Watt
output6 +30.0/0-20mA/+27.9-32.1(
voltage limit)/7%tolerance/0.6Watt
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.
Output1\2\3:50mV at peak-peak line Ripple;200mV at peak-peak Switching Ripple.
Output4\5\6:100mV at peak-peak line Ripple;200mV at peak-peak Switching Ripple.
