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 24.0V±5％ when the load is 0A~10.0A steadily
This Power can work from 0A~10.0A and output voltage is in section 2.2 specified range
Output Ripple voltage is 400mV peak to peak or less.(100Vac 60Hz/240Vac 50Hz)
＊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:
The power shall support 11.0A for 20S at 100~240Vac and 25℃
2.9 Load transient response:
The power must within regulation when applied a step load from 0% to 50% and 50% to 100% load at 0.5A/uS slew rate and 10mS time period.
The output voltage will be performed 22.8V~25.2V
2.10 Output regulation
+ 24.0 V
± 5 ％
± 1 ％
± 5 ％
＊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.
3.1Over Voltage Protection:
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)
