The KCG2 series automatic charger uses high‑frequency PWM technology with IGBT and MOSFET power devices, providing a compact switch‑mode power supply for battery charging. It operates in three stages—balance charge, constant‑voltage charge, and float charge—to fully charge and maintain batteries.
The manual describes installation requirements, control panel layout, model dimensions, charging mode selection, accessory settings, and fault handling, along with detailed technical specifications such as input voltage range, output capacity, efficiency, and protection functions. This manual is written in Chinese.

Use the manual switch on the front panel to choose “均充” (balance charge) or “浮充” (float charge).
Yes, a fine‑tuning potentiometer on the upper right of the panel allows small adjustments of the constant‑voltage setpoint.
Install the unit away from heat and water sources, and keep at least 10 cm clearance around the vent for proper airflow.
