Input Frequency:
47~63Hz single phase
Input Current:
6A (RMS) at 115VAC at without AC outlet; 3A (RMS) for 230VAC
Inrush Current:
70A at cold start
Switching Frequency:
30KHz typical
Hold Up Time:
16ms min.
Brown Out Voltage:
95V~max. 60Hz
Output Power:
250W at 45°C
Power Up Time:
< 20ms for +5V output voltage
Power Good Signal:
The power good signal will not be higher than 100~500ms after the +5V output stabilizes at its operating value when the unit is turned on
Power Failure:
The TTL compatible signal will go down at least 1ms before +5V below 4.75V
