V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062
Conditions/Description
At 90 VAC full load
Peak measured at 230 VAC and full load, cold start
Active power factor correction meets EN61000-3-2 class D
Conditions/Description
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.
At 230 V and full load
At 120 VAC
At 120 VAC and 80% of rated maximum load
Output user adjustable
Designated as RS+ and RS- on the CN3. Total voltage
compensation for cable losses with respect to the main output.
Defined RSW on CN3, requiring a low signal to inhibit output
Green - the power supply is operating normally.
Orange - when any protection occurs or RSW is low.
Designated as PG on the CN3. This signal goes high 100-500 mS after the output
reaches regulation. It goes low at least 1 mS before loss of regulation.
Designated as CSH on the CN3, optional single wired for forced surrent sharing function
and parallel up to 4 units within 10% accuracy at full load.
Designated as CMN on the CN3 for for current sense for a 0.5 V 3 VDC to represent
0% to 100% output current.
Designated as ACF on the CN3 to monitor the input voltage when input goes under 80 ± 5
VAC the signal will go low (0 V) and then go high (+5 V) once it reappears over 86 VAC.
Conditions/Description
Built-in ac fuse. A blown fuse usually indicates permanent
damage to the power supply serviceable by factory only.
Power supply shuts down when ac input is under
80 ± 5 VAC. When ac line reappears over 86 ± 5 VAC,
the power supply restarts automatically.
Current limiting starts at 110-140% of the rated output current and
recovers automatically.
Short circuit can be continuous. Recovers automatically upon removal of short.
Output is protected against 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.
