4 Output Characteristics
4.1 Static Load
Voltage Minimum load Maximum load
+5V 0A 1.0A
4.2 Output Voltage
The output voltage shall be statically regulated for all combinations of load, line and
environment including cross regulation as shown.
Voltage Range Tolerance
+5V +4.90V~5.20V ±5%
4.3 Ripple & Noise Voltage
Voltage 5V at full load
Ripple & noise voltage
Measuring is done by 20MHz bandwidth oscilloscope and terminated each output with a
10uF capacitor and a 0.1uF capacitor
4.4 Hold-UP Time
10 msec minimum from loss of nominal AC input at full load condition, 110VAC/60Hz
input, output will remain within regulation
4.5 Efficiency
The efficiency (watts out / watts in) is higher than 70% typical while measuring at
nominal line and rated load
<100mVp-p
4.6 Turn on delay time
During turn on and turn off, no voltage shall exceed its nominal voltage by more than
2% and no output will change its polarity with respect to its return line. All output shall reach
their steady state values within 1 seconds of turn on.

5 Protection Requirement
5.1 Short Circuit Protection:
The adapt er is protected that a short happened between the output terminals and shall
not result in a fire hazard, any damage to this adapter and will be normal operation
automatically while the short is removed.
5.2 Over Voltage Protection
The power supply shall be shutdown when5V output voltage reaches to its over –
voltage protection trigger point 9.0V Max
5.3 Over – current protection
No damage to the power supply shall be sustained when operating any output
under any line condition, into an over load condition for an indefinite period of
time. The power supply shall be self – recovering when fault condition remove.
6 Environmental Requirement
6.1 Operating
