Frequency change range: 47-63Hz

1.2 Input Current

At low line AC and full load, the maximum input current is 0.5A

1.3 Input protection

When the AC input voltage has surges and abnormal conditions, the 2A fuse will protect the power supply

1.4 Input surge current

At 25°C ambient temperature, when the input is 230Vac cold state, the maximum inrush current is 60A

More than 81.39% min of average efficiency of 25%,50%,75% and 100% load tested at115Vac and 230Vac.(5V/3A Warm up after 30 minutes)

More than 85% min of average efficiency of 25%,50%,75% and 100% load tested at115Vac and 230Vac.( 9V/2A，12V1.5A Warm up after 30 minutes)

1.6 No Load Power consumption

In the case of rated input AC and output no-load, the maximum no-load loss is 0.1W

1.7 Hold up time

In the case of rated input AC and output full load 3.6A, the minimum holding time is 10ms.

2.0 Output Characteristics

2.1 Turn on delay

In the case of 230VAC voltage input and output at full load, the maximum power-on delay time is 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 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 264Vac

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

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, 90-264Vac input 25℃ambient temperature).

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

(Test conditions: at full DC output, 90-264Vac input, and 25°C ambient temperature, a 10uF electrolytic capacitor and a 0.1uF ceramic capacitor are connected in parallel at the output)

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

Test methods: Short FB Pin to GND:

Leakage current 0.25 mA max@240VAC

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