NRS Heavy Duty Battery Chargers

Features:

  • Temperature compensated with control limits
  • SCR Regulation – Charger provides a constant current and constant voltage charge as well as an excellent AC line regulation for precise control.
  • Selectable Float Voltage – Allows battery voltage to be precisely set to the battery manufacturer specifications, within 0.10 of a volt.
  • Positive Voltage Setting – Select only the voltage setting. No other setting required. If preferred, voltage can be pre-set at the factory.
  • External Temperature Probe – Charger will monitor the exact battery temperature, which prolongs battery life and reduces maintenance caused by excessive heat and water loss.
  • Dual Input Voltage – Charger has been designed for either 115 or 230 volts AC.
  • Transient Protection – AC input and DC output have surge protection
  • Battery Types – All maintenance-free cells, lead acid cells, and nickel cadmium cells
  • All input/output connections are AAR standard binding post enclosed in a protective hinged cover.
