DC 12-24V Car Refrigeration Air Compressor Fridge Freezer Marine Solar

DC 12-24V Car Refrigeration Air Compressor Fridge Freezer Marine Solar

• Installation: Insert the three-phase output plug of the controller tightly into the terminal of the compressor, and tighten the screws after the controller is set into the mounting card of the compressor
• The controller automatically adapts to dual voltage, i.e. DC 12V and 24V power input systems; The maximum input voltage is 17V for DC 12V systems and 31.5V for 24V systems
• External Fan: A 12V DC fan can be connected between the terminals (F+) and (F-) of the controller, the positive terminal of the fan is connected to the (F+) terminal of the controller and the negative terminal is connected to the (F-) terminal of the controller; The output between terminals (F+) and (F-) will always remain at 12V when the input voltage to the controller exceeds 12V; The fan must be a 12V DC fan regardless of whether the input voltage system is 12V or 24V
• The operating temperature of the controller is not greater than 50°C; when the temperature of the controller case is too high, the compressor will be stopped and over-temperature protection will be generated
• Temperature switch: The temperature switch is connected to the C and T terminals of the controller; If no resistor is connected in between, the compressor will run at 2000rpm when the temperature switch is closed
