KCG2 Automatic Battery Charger
IGBT, Power CMOSFET and PWM IC controller have been contained in the KCG2 battery chargers (Power Converter). They are automatic high frequency switch mode battery chargers. Switch mode technology makes them light, compacted, quiet and have an accurate charge characteristic. 3-stage charging system (limited current, equalizer and floating) makes a complete charge and long battery life.

Application for:
Lead Acid Battery, Sealed lead acid battery, Alkaline battery, etc.
Marine vehicle, electric vehicle, golf cart, forklift, airplane, train, tank, etc.
