conditions/description
90-132 / 180-264 auto-selectable
At 100-120 VAC
At 200-240 VAC
Peak measured at 230 VAC at full load, cold start
Peak measured at 115 VAC at full load, cold start
Passive power factor correction meets EN61000-3-2 class A
conditions/description
Output voltage returns to within 1% in less than
2.5 mS for a 50% load change. Peak
transient does not exceed 5%.
Turn-on and turn-off overshoot shall not exceed
5% over nominal voltage.
Measured at 230 V and full load
3.3 model:
5 V model:
12 V model:
All other models:
At 120 VAC
At 120 VAC and 80% of rated maximim load
Adjustable with built-in trim pot.
When green (LED1) is on the power supply is operating normally.
Designated as PG on the CN1. This signal
goes high 100-500 mS after the output reaches regulation.
It goes low at least 1 mS before loss of regulation.
12 VDC/300mA for external fan
conditions/description
Built-in ac fuse. A blown fuse usually indicates permanent
damage to the power supply serviceable by factory only.
Current limiting starts at 110-140% of the rated output current in foldback mode and
recovers automatically.
Short circuit can be continuous. Recovers automatically upon removal of short.
Output is protected agaist overvoltage. Unit shuts down and latches
when voltage at output terminals exceeds 130%. AC input needs to be
reset to restart the power supply.
Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery.
