2 / 5 page rev. page date DESCRIPTION: switching power supply 2 of 5 11/2010 20050 SW 112th Ave. Tualatin, Oregon 97062 phone phone 503.612.2300 fax www.v-infinity.com fax 503.612.2383 PART NUMBER: VF-D320-DXXXA-CFS INPUT parameter conditions/description min nom max units input frequency 47 63 Hz input voltage 90-132 / 180-264 auto-selectable 90 264 VAC Input current At 100-120 VAC 8A At 200-240 VAC 4A inrush current Peak measured at 230 VAC at full load, cold start 70 A Peak measured at 115 VAC at full load, cold start 35 A power factor Passive power factor correction meets EN61000-3-2 class A OUTPUT parameter conditions/description min nom max units transient response Output voltage returns to within 1% in less than 2.5 mS for a 50% load change. Peak transient does not exceed 5%. overshoot Turn-on and turn-off overshoot shall not exceed 5% over nominal voltage. efficiency Measured at 230 V and full load 75% turn on delay At 120 VAC 1 second hold up time At 120 VAC and 80% of rated maximim load 20 ms adjustability Adjustable with built-in trim pot. +/- 5% LED display When green (LED1) is on the power supply is operating normally. power good Designated as PG on the CN1. This signal goes TTL high 100-500 mS after the output reaches regulation. It goes low at least 1 mS before loss of regulation. fan drive 12 VDC/400mA for external fan PROTECTION CIRCUIT parameter conditions/description input fuse Built-in ac fuse. A blown fuse usually indicates permanent damage to the power supply serviceable by factory only. overload Current limiting starts at 110-140% of the rated output current in foldback mode and recovers automatically. short circuit Short circuit can be continuous. Recovers automatically upon removal of short. output over-voltage 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. over temp. Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery. |
