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.

2.2DC output regulation

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

＊Line regulation is measured from 81vac to 300vac

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

230Vac nominal AC input voltage

＊A dynamic load state is the instantaneous current 1.3 A, every time last 45S,

1.3A reach 20% duty cycle with 1S, 0.9A reach 80% duty cycle with 4S, the current rate 1 A/us, refer to the below waveform

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

＊The test condition of linear adjustment rate is 81Vac to 300Vac

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

＊The instantaneous load in the ringing state is 1.3A, the total time of each ringing state is 45S, the duty ratio of 1.3A is 20%, each time is about 1S, the current change rate is 1A/us, please refer to the waveform below

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
