This guide explores the wiring methods for Guchen 12V electric AC compressors, focusing on 3-speed rotary switch and PWM control models. It explains the differences in wiring, step-by-step instructions for both methods, and answers common questions about compressor performance and control.

This article explores the critical stages of pre-charging, where Guchen Industry's advanced pre-charging resistor modules protect the compressor and battery from current surges, the simultaneous high-voltage and low-voltage power supply phase, and the CAN communication-based command execution.

Electric compressors feature two connectors: a low-voltage side and a high-voltage side. Low-voltage side is equipped with 6 (or 8) pins, with 4 pins dedicated to CAN communication. High-voltage side features two main pins for the high-voltage power supply positive and negative, along with high-voltage interlock pins.
