Rectifier Specifications, R48-500 and R48-1000
AC Input
Nominal Voltage 120, 208, 240VAC
Operating Voltage Range 85 to 300VAC
Frequency 45 Hz to 65 Hz
Power Factor (PF) >0.90 for 25%-50% load, >0.98 for 50%-100% load and >0.99 for 100% load
at 208Vac, 220Vac, 230Vac, 240Vac and 25°C
Total Harmonic Distortion <5% from 50 to 100% of rated load at 208 Voc – 240 Voc
Input Current Max 6.5A both 500W and 1000W
Inrush Current Inrush current does not exceed 150% of the rated input steady state peak value
Operating Efficiency 91% (500W) 92% (1000W)
DC Output
Output Voltage Range -42 to -58VDC
Output Power Constant power limiting operation 500W and 1000W @ -48VDC
(for 1000W, see derating chart for voltages less than 176VDC or temperatures higher than 45°C)
Output Current 10.42A @ -48VDC (500W) 20.83A @ -48VDC (1000W)
Regulation Steady state output voltage remains within +/-1% for any combination of input voltage and temperature
from 5% to 100% load
Voice Band Noise The voice-frequency noise generated by a rectifier does not exceed 32dBrnC output noise from 0% to 100% load
Wide Band Noise Does not exceed 250mv peak-to-peak, or 100mv rms per Telcordia GR-947-CORE
Psophometric Noise <1mV at 0 to 100% of rated load; <32dBrnc at 0 to 100% of rated load (output voltage > -42V)
Protection High Voltage Shutdown fixed and selective capability. Fixed – requires manual restart.
Selective – If rectifier detects over voltage it will turn off. After 5 seconds it will restart;
if it encounters an over voltage within 5 minutes it will turn off and remain off until reset.
Environmental

Altitude 2000m, 6560 ft at full power
Ventilation Front to back with speed-controlled fan (field replaceable)
Audible Noise The rectifier does not produce sound levels above 53dB(A), measured 0.6m in front of the rectifier, at the same hori-
zontal line as the middle of the rectifier at 25°C
