Wiring Information

This electric AC Compressor is very simple to wire in, with 2 Looms in total; one for power and one for control two rocker switches or a 4 position rotary switch required to control the compressor speed.

Port	Wire Colour	Definition
Power	Orange	48v DC positive input
Earth	Orange	48v DC negative input

Port	Wire Colour	Definition
12v Positive	Red	12c DC positive input
12v Negative	Black	12v DC negative input
STB	Brown	The AC start-stop enable signal input, high level or floating is closed (OFF), low level is open (ON). Input level range: high level range 5-15v DC, 15mA; low level range 0-0.8v DC, 22mA
PWM In	Grey	Air conditioner speed control signal input, the signal frequency is 1kHz PWM duty cycle signal. Input level range: high level range 5-15vDC, 20mA; low level range 0-.08vDC, 15mA. Speed adjustment range: 2000-6000 rpm, corresponding to PWM duty cycle 5%-95% linear change. 2000rpm corresponds to positive duty cycle of 5% and 6000rpm corresponds to positive duty cycle of 95%.

We also carry a wide range of automotive wiring products such as relays, fuses, terminals, cable, switches & more.
