A-6 

These are the electrical specifications:

• Power Factor: 0.98 W/VA

• Inrush Current:

- 40A peak at 115 VAC for one line cycle

- 40A peak at -36 VDC within 4 msec.

• Efficiency: Less than 65% at full load, nominal line

• Output Power: 350 watts

• Hold-Over Storage: 20 msec at full load, 90 VAC

• Transient Response:

- All outputs return to 1% within 2 msec of a 25% load change.

• Dynamic Load: 

- This power supply operates properly when subjected to a 10% load delta 

with a 50% duty cycle, from 0 to 2 MHz.

• Over Voltage protection:

- +5V output <6.4 VDC

- +3.3V output < 4.2 VDC

• Short Circuit Protection:

- Short between outputs causes latch off.
