I'm selling a DC Power Supply made by "POWER ONE". Model Number NRG275-3000F. If you don't know much about Power Supplies, "POWER ONE" is top of the line. These units I am selling were use to copy a Computer Hard Drive to several blank drives. This was a one time deal, so these units are virtually brand new. They are a little scuffed up from being moved around and stored in a cabinet...but they are hardly used. Some were never used. Its a HEAVY DUTY supply that can be used for many applications, and with 12 Volts @ 25 Amps, you could charge a car batter with it! It has a "bus bar" on it with screws so that you can attach wires to the different DC outputs and AC inputs. Currently is has standard PC drive connectors attached to "Y" Cables that were custom made by a wiring company....you can remove them if you want. AC input cord is about 7 feet long and heavy duty. This whole setup cost over 150 dollars by the time I was done but saved us thousands. Input can be either 110ac or 220ac and is fully automatic. Automatic selecting dual range 85-132 VAC or 170-264 VAC. 47-63Hz single phase. NOTE: AC Input range selection is fully automatic. No manual switchover is required. See Voltage/Current Rating Charts. See Voltage/Current Rating Charts. See Voltage/Current Rating Charts. Sixty second maximum peak power durations. A 10% duty cycle is not to be exceeded when peak power durations are combined. Regulation is maintained down to 85/170 VAC, at full rated load, with no compromise in performance. 20 msec minimum at full rated load and nominal AC input voltage. TTL compatible signal will be low when the main output voltage is beyond plus or minus 10% of nominal. TTL compatible signal goes low 4 msec before the main output drops to 95% of its steady state value at full rated load. Measured at full rated load and nominal AC input voltage. 75% ±5% depending on how the load is distributed among the outputs. See Voltage/Current Rating Charts for individual model ratings. Line: Measured over an 85-132 VAC or 170-264 VAC line change. Load: Measured over a min to max load change. Multiple output model regulation is subject to the minimum load requirements Measured at 50% of full rated load on all outputs. The following minimum loads are required on the main output to All output: Less than 1 msec typical for a 50-100% load change and recovery to within 1% of initial voltage set point. Maximum excursion: 3% from initial voltage set point. 1% PK-PK maximum on any output (20 MHz bandwidth) Initiates shutdown in the event of an overtemperature condition. Power-Up Initialization Period: 2.0 sec. maximum turn-on delay assures orderly ramp-up and stabilization of all output voltages during power-up. AC input line fuse provided. Internally located. Internally limited at 80A PK, cold start. Operating: 0°C to 50°C at full rated output power. Derate linearly to 50% of full load from 50°C to 70°C. Forced air cooling of 300 LFM is required if the internal fan option is not used. Cooling air velocity is measured 1/4" above, at the middle of the chassis. Air flow direction is from the input section Operating: 5-32 Hz and 32-5Hz, Sinusoidal, 0.02 in(DA). 32-2000 Hz and 2000-32 Hz, Sinusoidal, 1g(PK). Non-operating: 10-350 Hz, 0.04 g2/Hz. 350-2000 Hz, 0.007 g2/Hz, 6.15g(RMS) overall. Operating: 10 ±3msec, 3 axes, Half Sine, 20g(PK). Non-operating: 10 ±3msec, 3 axes, Half Sine, 40g(PK).
