R48-5800 Rectifier – Electrical Specifications*
AC Input
Nominal Voltage Three phase 380/480VAC
Operating Voltage Range R48-5800: 304VAC to 530VAC (output reduced 50% from 260-304VAC)
R48-5800L: 145VAC to 230VAC (output reduced 50% from 145-176VAC)
Frequency 45 Hz to 65 Hz
Power Factor (PF) >0.98 from 50% to 100% load
Total Harmonic Distortion <5% from 50% to 100% load
Input Current Max 20 amp
Inrush Current Inrush current does not exceed 150% of the rated input steady state peak value.
Input Protection If the input voltage decreases or increases beyond a non-adjustable predetermined value, the recti-
fier circuitry shuts down, disabling the output. The rectifier will recover automatically when the
AC input is re-established and exceeds 260VAC (low voltage restart point) or when it decreases to
530VAC (high voltage restart point). Overcurrent is protected by an internal fuse.
Operating Efficiency 93% peak
92.6% at full load
DC Output
Output Voltage Range -42.0VDC to -58.0VDC
Output Power 5800W maximum from 304VAC to 530VAC
Output Current Nominal 110 amps, adjustable from 10-110 amps
Regulation Steady state output voltage remains within +/-0.25% for any combination of input voltage
from 5% to 100% load
Voice Band Noise The voice-frequency noise generated by a rectifier does not exceed 32dBrnC output noise
from 10% to 100% load
Wide Band Noise Does not exceed 250 mv peak-to-peak, or 100 mv rms per Telcordia GR-947-CORE
Psophometric Noise Does not exceed 1 mv from 10% to 100% load
Protection
Current Limiting The output current is limited to 110 amps
Over Current Internal fuse
High Voltage Shutdown 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.
