Detailed Switching Power Supply ( Psb140 ) Description
1. Input Characteristics:
a. Input Frequency:50 / 60HZ±10%(45HZ - -)
c. Input voltage:110 - 230VAC±15%(90VAC - )
b. Fuse: A frse is included in the AC line circuit. Inrush Current:<20A / ms. The fuse rating is as to prevent
Safety hazard in the event of an intemal failure of the power supply.
d.
e. Earth Leakage Current: The earth leakage current does not exceed 0.25mA at 264VAC
66Hz Input and the Min load condition.
f. Output Specification
a. Efficiency:75%min, at 220VAC input full load test.
2. 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 ) / 5%tolerance / 4.95Watt/
output2 +5.00 / 50 - 800mA / +4.75 - 5.25(
voltage ) / 5%tolerance / 4.0Watt
output3 +12.0 / 0-100mA / +11.4 - 12.6(
voltage ) / 5%tolerance / 1.2Watt
output4 +16.0 / 0-450mA / +15.0 - 17.0(
voltage ) / 7%tolerance / 7.2Watt
output5 +23.0 / 0-450mA / +21.8 - 24.2(
voltage ) / 5%tolerance / 10.35Watt
output6 +30.0 / 0-20mA / +27.9 - 32.1(
voltage ) / 7%tolerance / 0.6Watt
b. Line ripple: measured
with an oscilloscope with a bandwidth of 100 MHZ. Output Ripple: Measurement of ripple includes a 0.1uF ceramic capacitor and a 47uF
electrolytic capacitor at the output of measuring oscilloscope. Switching ripple: measured
with an oscilloscope with a bandwidth of 100MHZ.
Output4\5\6:100mV at peak - peak line Ripple;200mV at peak - peak Switching Ripple.
Output1\2\3:50mV at peak - peak line Ripple;200mV at peak - peak Switching Ripple.
c. Turn on delay time:1S max, at normal line full load.
d. Over Current Protection: The power supply protects itself from any over current
conditon. Hold on time:20mS min, at 220Vac line max load.
e.
f. Thermal Protection: The power supply Protects itself down if it overheats. Shorted Output: All output with stand an indefinite short to Gnd, under any load
condition on the other output. It resets
itself with no operator inventon.
g.
h. HI - pot Test: Dielectric Withstand Voltage ACinputL. Burn - In: All power supplies will go through 4 hours of burn - in at 40 temperature
chamber under the nominal input and 80% of the maximum load condition, before delivery
to AMP. N to all output connectors 3000VAC
for 1 minute TEST.
i.
j. PCB Dimensions and Weight: Size:144*59*26(L*W*). Weight:0.20kg MAX
