Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.

Mode ABJ-N Power Protection Module for Compressors is one of the power protecton modules independently researched and developed by our company. It can serve as a substitute for the mainstream NTC power protection modules (such as INT79) in the current market. The product has high reliability, high accuracy, high cost performance, and clear fault display. Input voltage on the three-phase protection end covers rated voltage in various countries across the world, while 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 different electric supplies in various countries around the globe. 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 NTC temperature protection, monitoring the compressor temperature and the discharge temperature respectively
· Switching value protection: Oil flow, oil level, and oil filter
