The new MicroSMART charger from SBS provides you with a 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
  • Advanced precision control for best battery life
  • Display and control panel permit simple programming
  • Archived charge data: 1,800 cycles
  • 480VAC 3 phase, 60Hz
  • Wireless radio standard on all MicroSMART chargers


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.

Graphic Display

The backlit LCD display offers adjustable brightness and contrast for ease of viewing in a variety of lighting conditions. The display can have up to six lines of information and also displays information graphically.

Wireless “Best Battery” Choice

The ability to communicate between chargers allows the chargers to display the next available battery in a particular group, based on the length of time since the battery was completely charged. You can set up as many as 999 different groups. This ensures that all batteries receive equal usage and helps to promote a first in – first out battery rotation. This capability is standard in all MicroSMART chargers and can be implemented without additional hardware. In addition to the charger display, the next battery available can also be viewed on a remote terminal display.

Wireless Maximum Power Limit

The wireless feature of the Access charger allows you to limit the AC power that a particular group of chargers are allowed to draw. This feature may be used where AC power is limited, or in applications where you don’t want the power consumed by the chargers to push your total power demand costs higher than necessary.

AGV Option

With the addition of an optional PC board, the charger communicates with many popular AGV charging systems. This ability to communicate with the AGV allows them to pull into a charging station and receive an optimum charge automatically.

Ionic Mixing Option

When the Ionic mixing charge curve is selected, the charger pulses the output current during the finish portion of the charge cycle resulting in brief periods of increased gassing. This gassing action improves the mixing of the electrolyte without increasing electrolyte usage. This ensures that the heavy acid at the bottom of the cell is thoroughly mixed throughout the cell, preventing stratification and extending battery life.

Gassing Block-out

All the opportunity charge curves include a gassing block-out period that prevents the charger from entering the gas-producing, finish charge stage for the first two hours that the battery is connected to the charger. In opportunity charging, it is critical to return as many ampere hours as possible in the limited time available. For this reason, the charger does not shut down when it reaches the gassing point, but simply reduces the charge current to minimize gassing.
