1.2 Input Current
0.3A max
| At AC low line input and DC output full load |
At low line AC and full load, the maximum input current is 0.3A
1.3 Input protection
5A Fuse
| The power supply shall be protected against power line surges and any abnormal condition. |
When the AC input voltage has surges and abnormal conditions, the 5A fuse will protect the power supply
1.4 Input surge current
30A max | At power supply cold start, ambient temperature 25ć˜230Vac |
When the input is 230Vac cold state at 25℃ ambient temperature, the maximum surge current is 30A
1.5 Efficiency
1.5.1 68 %min. At nominal input voltage,maximum load and measured at end of DC cable
1.5.2Active mode efficiency
More than 68% min of average efficiency of 25%,50%,75% and 100% load tested at115Vac and 230Vac.(Warm up after 30 minutes)
1.6No Load Power consumption
0.3W rms max
| At AC nominal input˜output no load |
In the case of rated input AC and output no-load, the maximum no-load loss is 0.3W
1.7Hold up time
30ms min | At 230VAC nominal input˜ output full load |
(1 half cycle) |
Under the condition of rated input 230V AC and output full load, the minimum holding time is 30ms.
2.0 Output Characteristics
2.1 Turn on delay
2S max
| At 230VAC voltage input˜output full load |
In the case of 230VAC voltage input and output at full load, the maximum power-on delay time is 2S
Test on delay is measured from 0 voltage output to the main output regulation.

+5.0 | 0 | 1.0 | None | 4.90~5.50 | |
Total regulation involved line regulation load regulation cross regulation---etc.
Line regulation is measured from 90Vac to 132Vac or 185vac to 264vac
Load regulation is measured all output from min load to max load at 115vac or 230vac nominal AC input voltage
2.3 Ripple/noise
Voltage(V) | Ripple/Noise(pk-pk)(mV) |
+5.0 | 100 |
The ripple is measured from peak to peak with band width limit of 20MHz
(By passed at the end of connector with 10uF electrolytic and 0.1uF ceramic disk capacitor under
DC output full Load, 90-264Vac input 25 ambient temperature)
3.0 Protection
3.1 Short protection / Over current protection
The power supply will self-protect any output to ground, And auto recovery when abnormal circuit faults remove.
An output short circuit is defined as any output impedance of less than 0.1 ohms.
