Input Current: 5.5A at 90 VAC full load.
Power Good: Power on signal designated as PG on PCB
goes high 100-500 mS after the output reaches the
regulation limit. It goes low at least 1 mS before loss of
regulation.
Operating Temperature: 0°C to +50°C
Storage Temperature: -20°C to +85°C
Inrush Current: 70A peak maximum (Measuring at
230 VAC and full load cold start).
PFC: Power factor correction meets EN61000-3-2 Class D.
Fan Drive: 12 VDC/160 mA offering to drive an external fan.
Transient Response: output voltage returns to within 1% in
less than 2.5 mS for a 50% dynamic load peak. Does not
exceed 5%.
Overshoot: Turn on-off overshoot does not exceed 5%
nominal voltage.
Efficiency: 70% for 3.3V, 75% for 5V, 80% for 12V and
82% minimum for other outputs (Measuring at 230V and
full load).
Turn On Delay: 1 second maximum at 120 VAC.
Hold Up Time: 20 mS minimum at 120 VAC and 80% of
rated maximum load.
Adjustability: Output user adjustable ±5% minimum.
Input Circuit Protection: 250V/6.3A fuse inserted.
AC Under Voltage Protection: Power shuts down if Vin
goes under 79V ±2V. Automatic recovery once Vin goes
back over 86V ±3V.
Operating Humidity: 5% to 90% RH, Non-condensing
Storage Humidity: 5% to 95% RH, Non-condensing
Vibration: Frequency 5 to 50 Hz, acceleration ±7.35
M/(SxS) on X,Y and Z Axis
