COMPANY PROFILE

HEAVY DUTY BATTERY CHARGERS

  • Temperature Compensated with control limits.
  • SCR Regulation --- Charger can provide a constant current and constant voltage charge as well as an excellent AC line regulation for precise contol.
  • Selectable Float Voltage --- Allows the battery voltage to be precisely set to the battery manufacturer specifications, within a 10th of a volt.
  • Positive Voltage Setting --- Only select the voltage setting, no other setting required, or the 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.
