2. Output Characteristics.
2.1 Rated Voltage
The rated output voltage is specified at 24.0V
2.2 Voltage Range
The output voltage will be performed 24.0V5% when the load is 0A~10.0A steadily
2.3 Current
This Power can work from 0A~10.0A and output voltage is in section 2.2 specified range
2.4 Ripple/noise
Output Ripple voltage is 400mV peak to peak or less.(100Vac 60Hz/240Vac 50Hz)

Measured methods:
*The ripple is measured from peak to peak with band width limit of 20MHZ (C1 : 0.1uF Ceramics capacitor C2 : 47uF/50V Aluminum capacitor under DC output full Load, AC nominal input 25℃ambient temperature).

2.5 Turn on delay
The power shall switch on in less than 3 seconds at input voltage is 200Vac
2.6 Hold-up time
The output voltage shall be sustained 6mS within regulation requirement after loss 200Vac and maximum load
2.7 Rise time
DC output rise time from 10% to 90% of output voltage shall be less than 40mS at nominal line and maximum load
2.8 Surge load:

*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.

3. Protection
3.1Over Voltage Protection:

Over Voltage Protection

The output shall be p rotection to latch off at over-voltage condition , maximum value cant be over 2 times the rated voltage (48V) , That might be return to normal state by AC reset <= 3.Minutes

The power supply will be auto recovered when faults remove

3.2 Over Current Protection: The maximum constant current would be greater than 11A and
less than 20A; The power would be auto-recovery
3.3 Short Circuit:
Output can be shorted without damage No odor, smoke, fire, plastic deformation, and excessive
heat happen. The power shall be auto-recovery. (It will enter into normal condition when then the fault condition is removed)
