Product Description

Key Benefits:
1. Operated by DC power source, widely used on vehicle A/C systems, like electric car/electric bus/truck and other vehicle markets;
2. Small size, light weight, easily installation;
3. Scroll type compressor, with higher efficiency and good reliability; Low vibration and quiet operation;
4. Voltage widely ranges from 12V to 900VDC, and cooling capacity ranges from 1.0kw to 3.0kw(,24V,18cc items), 1.8kw to 5.4kw(27cc items);

 

1. Features and Parameters

2.1 Main functions and features

1) Drive controller and compressor split design;

2) Undervoltage protection: Undervoltage is 11±0.3VDC. After undervoltage protection, after the voltage returns to 13±0.5VDC,

Can be reset and restarted;

3) Overvoltage protection. When the voltage in the circuit is higher than 18VDC, the drive controller will be damaged;

4) Overcurrent protection. When the current in the circuit is too high (greater than 60±3A), the drive controller will automatically cut off

The circuit avoids damage to the compressor and the drive controller caused by excessive current;

5) Compressor speed selection: the controller yellow and green lines are short-circuited to full speed (Note: the power becomes proportional to the speed

Chemical)

6) Anti-flying function: When the controller controls the gray line to be disconnected by high and low voltage protection, overheat protection, etc., control

The device stops working, and the system needs to be restarted after reset to operate normally.
