1.5 Efficiency

1.5.1 86.8 %min. At nominal input voltage,maximum load and measured at end of DC cable

Under rated input voltage and full load, the efficiency of the DC line end is 86.8% minimum

1.5.2 Active mode efficiency:

More than 86.8% min of average efficiency of 25%,50%,75% and 100% load tested at115Vac and 230Vac.(Warm up after 30 minutes)

At 115Vac/230Vac input, the average efficiency under 25%, 50%, 75%, and 100% load conditions is at least 86.8%

(Record data after 30 minutes of aging)

1.7 Hold up time

Under the condition of rated input AC and output full load, the minimum holding time is 10ms.

2.0 Output Characteristics

2.1 Turn on delay

When the AC 230V input and output are fully loaded, the maximum power-on delay time is 3S

＊Test on delay is measured from 0 voltage output to the main output regulation.

2.2 DC output regulation

＊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

＊The total adjustment rate relates to the cross adjustment rate of linearity and load

＊The test condition of linear adjustment rate is 90Vac to 132Vac or 185Vac to 264Vac

＊The test condition of the load regulation rate is the change from the minimum load to the maximum load in the case of 115Vac/230Vac input

2.3 Ripple/noise

＊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, 90-270Vac input 25℃ambient temperature).

*Ripple is obtained by measuring the peak-to-peak value using the oscilloscope bandwidth of 20MHz.

(Test conditions: at DC output full load, 90-270Vac input, 25°C ambient temperature, the output terminal is connected in parallel with a 10uF electrolytic capacitor and a 0.1uF ceramic capacitor)

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.

The power supply can automatically resume normal operation when the short circuit is removed

＊An output short circuit is defined as any output impedance of less than 0.1 ohms.

＊When the effective value of output impedance is less than 0.1 ohm, it is defined as output short circuit

3.2 Over voltage protection

3.3 Over Temperature Protection

No deformation and no discoloration on case and will be shut down. That will be return

To normal state by ac reset, reset≤2 minutes.

When the power supply is turned off, the shell is not damaged or stained. When the AC input is restored, the shell can be restored to a normal state, and the recovery time is less than 2 minutes.

4.0 Leakage current:

Leakage current 0.25 mA max@240VAC

When the input voltage is 240Vac, the maximum leakage current is 0.25mA
