EXZON battery chargers are solid­state controlled and are designed for charging stationary lead­acid or nickel­cadmium batteries. The charging characteristic conforms to IU­curve per the latest DIN41 773 for independent and parallel operation with the associated batteries. Many features are added without extra cost to customer.

​

        The rectifier chargers have been developed to conform to the National Electrical Manufacturer Association, NEMA­PE5, The Utility Type Battery Charger, and the Semi­conductor Converters standard, IEC 60146.

Features

• Soft-start Soft start is crucial when your charger needed to connect with the sensitive loads enabling the smooth start voltage and current will raise to the operating level over a 5­ second interval.

​

• Dynamic Behavior The charger output voltage will return to, and remain within, the deviation limit of voltage regulation not exceeding 2 seconds for step­load changing from 20% to 100% or 100% to 20% of rated output. No excursion of voltage results in activation of the overvoltage shutdown.

​

• Float and Boost charge To accommodate all battery types ­ lead acid, lead calcium, nickel cadmium : EXZON provides both float and equalize charge with separated voltage adjustment over a range of +10% of U2N. With Equalize Charging Mode, the output voltage increases to the equalize level within preset time ( 0­-24 hours) after that switches to the float level automatically

​

• Protection The charger includes the following protection features:­ ­

      - Input & output circuit breakers ­

      - High speed fuse for the power semiconductor (3phase) ­

      - Lightning arrester at both input and output sides ­

      - Auxiliary fuses

​

• Current Limiting The output current limit is factory­set at 100% of rated current to reduce output voltage for protecting battery from overcharge and charger from overload or short circuit. The output current limit can be adjusted over a range of 50­-110% of rated current.

​

• High voltage shutdown The output voltage is switched off automatically when the sensing circuit detects overvoltage (preset at + 10% of boost voltage) and switched on again automatically once the fault has been removed.
