The KCG2 series automatic charger is an automatic charger with high frequency PWM pulse width modulation technology, IGBT, field effect power tube and pulse width modulation integrated controller as the main components. This charger is a three-stage automatic charger (constant current equalization charging-constant pressure equalization charging-floating charging). It has overcurrent, overvoltage and overheating protection functions, and the output voltage and current LED digital display.
The KCG2 series automatic charger uses high‑frequency PWM technology and a three‑stage charging process (bulk‑charge, constant‑voltage charge, and float charge). It is designed to be compact, lightweight and more efficient than traditional thyristor chargers.
The manual covers technical specifications, model dimensions, installation guidelines, operation of the control panel, accessory settings, protection features, and troubleshooting procedures. It also includes formulas for selecting charging voltage and current based on battery type and capacity. This manual is written in Chinese.

Use the charging mode switch on the front panel; the switch can be set manually or the automatic accessory can change the mode according to the programmed timer.
The charger’s efficiency is not less than 80 %.
Install the accessory with the coded switch, set the ON/OFF positions for each function (e.g., bulk 8 h, float 7 days) and the charger will automatically switch modes according to the programmed intervals.
