Three-phase ARR chargers have 208, 240 or 480-volt input. DC outputs are either 130 volts at 50 to 500 amps or 260 volts at 25 to 250 amps. electrical Features standard control modules All three-phase ARR chargers, regardless of size, use the same plug-in printed circuit boards. This minimizes parts inventory and simplifies maintenance. regulation DC float voltage is maintained within ± 0.5 percent from no load to full load with input frequency variations of ±5 percent and with ac input voltage variation as shown. current limiting The current limiting circuit is factory set at 105 percent...
