UNDER / OVER VOLTAGE TEMPERATURE CONTROLLER WITH DEFROST
The N321R is a controller for refrigerated cooling applications with a defrost function for forced compressor shut-down . It accepts NTC , Pt100 and Pt1000 temperature probes , depending on the measurement ranges of the sensor which the user needs to know beforehand .
The N321R control output is capable of driving a compressor load of up to 1 HP directly . The features of a particular model ( there are seven different models in this range ) such as input sensor type , sensor range , mains supply and the likes are identified by the label placed on the thermometer body .
This model is also called the ‘ low voltage detector ’ Temperature controller due to the under / over voltage protection for compressors for power fluctuations supplied by Eskom , ideal for industrial refrigeration .
The defrost cycle is accomplished by the user turning off the compressor at time intervals with the Manual Defrost key positioned in the front panel for easy access .
