The promotion of energy-saving technologies surface is small, the penetration rate is not high

Not only saves energy, but also significantly reduce noise and temperature, and can extend the life of AC contactor. AC contactor energy-saving technology with a very large economic and social benefits. Currently on the market already exists AC contactor saving  mcb circuit breaker  a lot, but because of the problems have not been solved, leading to the promotion of electri cenergy meter echnologies surface is small, the penetration rate is not high. This thesis around the country AC contactor manufacturers and based on a survey of user needs, using self-designed a conversion program to achieve varying the duty cycle of the AC contactor energy ASIC chip ZDLX.
