CONTIS mini series of the battery chargers are designed for simpler industrial stationary applications - charging and keeping the station batteries charged, DC power supply and back-up of technological systems etc. Due to their excellent electrical parameters, they are suitable for lead-acid batteries, maintenance-free batteries - gel, AGM, etc.

Application and characteristic

The chargers are designed for a continuous supply of technological equipment and back-up systems (parallel operation with battery and load) without time limitation, keeping station batteries in a charged state and after discharging in case of power failure to recharge them. Cooling is provided by fans inside the charger. The rated (maximum) charging current is 40A. The output voltage is 12V or 24V as standard. Output current could be set in the charger.

CONTIS mini chargers use MOSFET high-frequency switching drives. Charging is controlled by a microprocessor control system. Important statuses are indicated by LEDs.
