2 / 5 page VPF-S800-XXR(I)-N Switching Power Supply Rev. 04-2007 2 / 5 V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258 Input Parameter Conditions/Description Min Nom Max Units Input Frequency 47 63 Hz Input Voltage 90 264 VAC Input Current At 90-264 VAC 12 A Inrush Current Peak measured at 230 VAC at full load, cold start 70 A Power Factor Active power factor correction meets EN61000-3-2 class D 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 12 V model: 80% All other models: 83% Turn on delay At 120 VAC 1 second Hold up time 80% of rated maximim load 20 mS Adjustability Adjustable with built-in trim pot. +/- 5% Remote sense Designated as RS+ and RS- on the CN3. Total voltage compensation for cable losses with respect to the main output. (NOT available for current sharing models.) Remote Inhibit Designated as RSW on the CN3. Requires a low signal to inhibit the output. LED display Green - the power supply is operating normally. (LED 1) Orange - when any protection occurs or when Remote Inhibit is in effect. Power Good 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. Current Sharing Designated as CSH on (CN3), use in parallel for forced current sharing function. Accuracy of shared current with up to 4 parallel units is within 10% at full load. Current Monitor Disignated as CMN on (CN3) for current sense purpose. CMN is a 0.5 to 3VDC output voltage to represent a linear 0% to 100% output current. 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. Input under-voltage Power supply shuts down when ac input is under 80 VAC. When ac line reappears over 86 +/- 5 VAC, the power supply restarts automatically. Overload Current limiting starts at 110-140% of the rated output current 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. |
