Addition to MicroStep-MIS family of intelligent chargers

Chargers are integral parts of Automatic Weather Stations. In case of hardly accessible or remote locations, reliable power supply is absolutely necessary.

Therefore, at MicroStep-MIS we are continually developing better and more reliable chargers. The purpose of the devices is not only to charge the batteries but also to deliver power to connected devices, to protect the battery, and to provide additional vital information about the charger itself, the battery and the sources.



A lot of power in a small case : SBIM
SBIM is the newest product of MicroStep-MIS. This intelligent charger is a low-cost solar charger with charging current up to 16 A. It supports automatic detection of 12 V or 24 V lead-acid batteries and its output provide power to connected devices with current up to 5 A. SBIM allows communication through the SDI-12 interface enabling access to important information and also possibility of adjusting various charger parameters. The low power consumption of 8.5 mW improves endurance of the power supply chain.

When each milliampere counts : BIM205
BIM205 is MicroStep-MIS flagship charger and it is one of the most versatile intelligent chargers on the market. BIM205 supports charging 12 V or 24 V lead-acid batteries from photovoltaic (PV) panel or AC/DC power source. Battery is charged with adjustable current up to 20 A and BIM205 is able to supply power to connected devices with current up to 5 A. Charging from PV panel is managed by MPPT (Maximum Power Point Tracking) function to get the most out of the the panel. BIM205 provides CC/CV (Constant Current, Constant Voltage) charging mode with temperature compensation of end charge voltage using the external thermometer. The charger has two communication interfaces: SDI-12 and RS232 being used to access necessary information. BIM205 has an LCD with backlight function to improve readability and internal protection against overvoltage, overload and reverse polarity connection.
