This unit is an off the shelf spare from Intel surplus. It has been tested and is guaranteed to work for 30 days, parts and labor, excluding freight.
The Unit's Serial Number Tag Reads:
Model Number: LFS-48-12
Serial Number: 9804R76213
Power Requirements: 95 - 132 VAC, 47-63 Hz / 187 - 250 VAC, 260 - 350 VDC / 18.4 A Max.
Specifications:
AC Input:
Line: +95 to 132 VAC / 187 to 265 VAC, 47-440 Hz.
Maximum Input Power: 1470 W
Maximum Input Current: 25.0 A RMS
Efficiency: 75% minimum
DC Input: 260 to 370 VDC on LFS-48 (unit must be wired for 220V configuration)
DC Output Voltage Range: 12 V ±5%
Regulation Voltage:
Regulation, Line: 0.1% from low line to high line and high line to low line.
Regulation, Load: 0.1% from 0 to full load.
Ripple and Noise: 20 mV RMS, 150 mV pk-pk
Temperature Coefficient: 0.03%/°C
Remote Programming Resistance: 1000 Ω/V nominal.
Remote Programming Voltage: volt per volt.
Overcurrent Protection: Current limiting with automatic reset.
Overvoltage Protection: Non-crowbar, inverter shutdown type OV protection is standard on all models.
In-Rush Current Limiting: All models are provided with in-rush current limiting to limit the current to a preset value.
Overshoot: No overshoot at turn-on, turn-off, or power failure.
Remote Turn-On/Turn-Off: TTL compatible voltage level signal enables remote turn-on/turn-off of the power supply. A voltage of 2.8 V to 5.0 V applied to remote on/off terminals will initiate turn-off. Open circuit or short circuit condition, or a zero to .5V signal will cause turn-on.
Remote Sensing: Provision is made for remote sensing to eliminate the effects of power output lead resistance on DC regulation.
Isolation Rating: 1500 VAC intput to output and 1500 VAC input to ground. 500 VAC output to ground.
Cooling: Fan cooled
Operating Temperature Range: Continuous duty 0°C to 60°C with suitable derating above 40°C. Guaranteed turn-on at -10°C with reduced specifications.
DC Output Controls: Screwdriver adjustment over the entire voltage range
Input and Output Connections: All input, sensing and remote on/off connections are made via PC board mounted terminal block. DC output connections are made via heavy duty bus bars. Ground connections are made via chassis stud.
Mounting: One mounting surface, multiple mounting positions.
Finish: Gray, Fed. Std. 595, No. 26081.
Dimensions: 5" x 4.875" x 11"
Weight: 12.31 lbs.
Safety Agency Approvals: All models are UL recognized, TUV licensed, and CSA certified.
