4 Output Characteristics
4.1 Static Load
Load Range
Output Voltage
Min Max
Regulation(V) Rated Power
USB 1: 5V 0A 1A 4.5~5.5V 5W
USB 2: 5V 0A 1A 4.5~5.5V 5W
If only use one USB Port: the Output Current: 5V / 2.1A
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 +4.50V~5.50V ±5%
4.3 Ripple & Noise Voltage
Voltage 5V at full load
Ripple & noise voltage <100mVp-p
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 86% typical while measuring at
nominal line and rated load
