A genset battery charger is an electronic device that uses AC mains supply to charge the genset's battery. This enables battery to support engine cranking process when required.

SEDEMAC's battery charger product range supports both 12V and 24V batteries and addresses the charging current requirements of 5A and 10A. SEDEMAC's battery chargers are also rugged and field-worthy devices certified to withstand a variety of extreme operating conditions in terms of temperature, vibration, humidity, short-circuit, a wide range of input voltage and so on.

  • The cost effective battery chargers are offered in compact, easy-to-mount packages to enable ready integration in a wide range of genset configurations
  • SEDEMAC's battery chargers adopt a configurable "switch mode power supply" design that helps reduce the energy losses and thereby improve the product life
  • Each product implements both charging modes - constant current and constant voltage and a plethora of diagnostic indicators to ensure trouble-free battery charging in the field.

  • Automated three stage battery charging features are provided to ensure longer battery life
  • Advanced switch mode supply design is responsible for higher output efficiency (>85%)
  • Manual boost mode results in fast charging
  • Built-in current and voltage protection circuit which gives effective protection against input over voltage, short circuit, output over current, reverse battery protection, input under-voltage shutdown, etc.
  • 4 LEDs are provided to indicate the operation modes and to diagnose the reverse battery connection
  • Can be used as Switched Mode Power Supply (SMPS) in manual boost mode
