3.4
Current Limit
Rectifier to automatically reduce its current limit set point with changes in ambient
temperature input voltage and output voltage. Current limit is of the constant current
type.
3.5
Load Regulation
1% from no load to full load.
3.6
Input Voltage
188Vac - 264Vac
3.7
Input Frequency
45Hz to 65Hz
3.8
Input Current
16 amps at full load.
3.9
Power Factor
Typical 0.98% at minimum 20% full load.
3.10 Efficiency
86%
3.11 Input Fusing
Internally fused at 20 amps in both the live and neutral lines.
3.12 Remote Sense
Total lead voltage drop 1V.
3.13 Temperature Co-efficient
Temperature range -25 degrees C to +55 degrees C +/- 0.015%/degrees C.
3.14 Series Output Diode
All rectifiers are to be equipped with a series diode in the positive output.
3.15 Alarm Signals and Lights
3.15.1
AC
-Green LED
Operates when ac input is above 188Vac, extinguishes as input voltage declines
to 180Vac.
3.15.2
DC Volts
- Green LED
Illuminates when the output voltage is above 48Vdc but below overvoltage trip.
3.15.3
DC Amps
- Green LED
Illuminates when the output current is above 15% of rated output current.
3.15.4
Fan Failure
- Red LED
Illuminates when the fan fails.
3.15.5
Over Temperature
- Red LED
Illuminates when the internal temperature exceeds 90 degrees C
Resets when temperature falls below 80 degrees C
3.15.6
High Voltage Shutdown
- Red LED
Illuminates when the rectifier output exceeds 60Vdc
–
the output shuts down.
