Electric AC Motor Speed Controller,Dual Motor Speed Controler

a. Scope of JECPS

It is of modular design, associated and coordinated with the functions of traditional circuit breaker, fuse, contactor, over-load relay, starter, and disconnector, intended for remotely or local manually controlled circuits, having front indications, signal alarm and time-current characteristics, and also available for control and protection of motors and distribution circuits by using optional modules or accessories.

b. Applications of Basic part JECPS on JECPSD-125Amp Electric AC Motor Speed Controller

With its advantages of integration, module, compact size, high protection degree, high breaking capacity, short ionization distance, longer life, continuity of service, high reliability and easy installation and maintenance, JECPS is suitable for control and protection of motors to be used in the field of metallurgy industry, coal mime industry, iron and steel industry, petrochemical industry, harbors and railway stations ect., and for control and protection of lightings, power transferring, pumps, ventilators and air conditioners in modern buildings, as well as for controlling and protecting of distribution system, motor control center(MCC), and factories or workshops.
