2.0Output Characteristics

2.1Turn on delay

In the case of AC low voltage input and output full load, the boot delay time is up to 3S

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

DC output regulation

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

＊Line regulation is measured from 90vac to 270vac

＊Load regulation is measured all output from min load to max load at 110Vac/220Vac

  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 270Vac

＊The test condition of load regulation is the change from the minimum load to the maximum load under the 110Vac/220Vac input condition.

*Full input voltage range; meets the instantaneous load of 4.6A in the ringing state, the total time of each ringing state is 45S, the 4.6A duty cycle is 20%, each time is about 1S, the current change rate is 1A/us

2.3Ripple/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 diskcapacitor under DC output full Load, AC nominal input 25℃ambient temperature).

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

(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 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

3.2Over voltage protection

Test methods: Short optical coupler 1Pin to GND

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,

When the power supply is turned off, the shell is not damaged or stained. When the AC input is restored, the power can be restored to normal state

Leakage current:

Leakage current 0.25 mA max@240VAC

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