SBS-MicroSMART RHF Battery Charger


The rapid high frequency MicroSMART industrial battery charger from SBS provides you witha powerful, energy-efficient battery charger in a sleek, lightweight package.

Utilizing a modern, state-of-the-art MOSFET power conversion circuit, the MicroSMART charger efficiently and accurately converts AC power to the proper DC power levels required to precisely charge an industrial battery.

High-Frequency Based Multi-Charger Benefits

  • Microcomputer smart charger
  • Charges all common battery types
  • High efficiency: 92%
  • High power factor: 0.95
  • Low weight and small volume

Batteries must be equalized on a regular basis to ensure maximum life. The MicroSMART charger facilitates this routine through its auto-equalize feature which allows equalize cycles to be programmed for a specific day of week or by number of complete charge cycles.

Energy-Saving Features

In addition to the energy efficient MOSFET design of the MicroSMART charger, the advanced control provides other energy-saving options such as charge block-out periods. Each day, up to three different periods may be blocked from charging. This feature can be used to avoid peak demand periods, time of day use billing, or any other reason why you may not want chargers running during a particular time of day.

Monday Morning Refresh

When a battery has been sitting over the weekend there is a certain amount of self-discharge that occurs. In order to provide a fresh, fully charged battery, you can program the charger to charge for up to 60 minutes prior to the start of the work week.


Every MicroSMART charger is equipped with a radio transceiver that allows the charger to communicate with other chargers as well as a host computer when equipped with the optional MicroSMART USB Gateway. The wireless communication system is FCC certified.

One Charger - Many Solutions

Within the power limits of the charger, every charger can be set to perform both conventional charging and various levels of opportunity charging. There are six different charge curves pre-programmed into every charger.
