2.0 Output Characteristics

2.1Turn on delay

Turn on time shall be <3S, the delay time is between AC being applied to output being within regulation

The start-up time from AC input to output reaching voltage regulation is less than 3 seconds

2.2Hold up time

In the case of rated input and output full load, the minimum holding time is 8mS

2.3DC output regulation

＊Total regulation involved line regulation load regulation cross regulation---etc.

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

＊Line regulation is measured from 90Vac to 264vac

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

＊Load regulation is measured all output from min load to max load at 115vac

or 230vac nominal AC input voltage

＊The test condition of load regulation is the change from the minimum load to the maximum load under the input of 115Vac/230Vac.

2.4Ripple/noise

The ripple is measured from peak to peak with band width limit of 20MHZ

The ripple is obtained by measuring the peak-to-peak value using an oscilloscope bandwidth of 20MHz

(By passed at the end of connector with 10uF electrolytic and 0.1uF ceramic diskcapacitor under DC output full Load, AC nominal input 25℃ambient temperature).

(Test conditions: at full DC output, rated AC input, and an ambient temperature of 25°C, a 10uF electrolytic capacitor and a 0.1uF ceramic capacitor are connected in parallel at the output end)

3.0 Protection

3.1 Output over current protection

The output shall hiccup when the over current applied to the output, and shall be self-recovery when the fault condition is removed.

When the overcurrent occurs, the output will enter the hiccup mode. When the overcurrent condition is removed, the product will automatically return to normal.

3.2 Output over voltage protection

3.3 Output Short protection

The input power shall decrease when the output is short to GND, the power supply shall not damage, and shall be self-recovery when the fault condition is removed

When the output is short-circuited to ground, the input power of the product is reduced and will not be damaged. When the short-circuit condition is removed, the product will automatically return to normal

3.4 Input over voltage protection

Remarks: When the input overvoltage state is released, the product returns to normal operation.

4.0 Leakage current:

Leakage current0.75mA max@240VAC

When the input voltage is 240Vac, the maximum leakage current is 0.75mA
