- product introduction:Model ABJ-R Power Protection Module for Compresors is one of the power protection modules independently researched and developed by our company. It can serve as a substitute for most of the PTC power protection modules in the current market. The product has high reliability, high accuracy, high cost performance, and clear fault display. Its input voltage on the three-phase protection end covers three-phase rated voltage in various countries across the world, while its input voltage on the working power supply end covers single-phase voltage and DC voltage in various countries across the world. In other words, you can use this one single product under diferent electric supplies in various countries around the globe. The product uses dual PTC protection input, which is able to protect different protection units respectively. This product is mainly used for the management of motors in screw compressors, exhaust systems, and fuel systems. It can also be used for the protection of other kinds of equipment with three-phase voltage.
Functions:
· On the three-phase protection end: Phase dislocation protection, dynamic & static phase loss protection, voltage unbalance protection
· On the temperature protection end: Two sets of PTC temperature protection, monitoring the compressor temperature and the discharge temperature respectively
· Switching value protection: Oil flow, oil level, and oil filter
