AC contactor AC contactor is widely used as power and control circuit breaking. It uses the main contacts for opening and closi

AC contactor

Feature

 Permanent magnet AC contactor is characterized by innovations in technology-driven organization with a permanent magnet to replace the traditional magnet drive, namely the use of permanent magnets and micro-electronics modules of the control unit, replacement of traditional products, electromagnetic devices, without running working current, only a weak signal from the current (0.8-1.5mA). Microelectronics module contains six basic parts.

1. Power rectifier;2. Controlling supply voltage real-time detection;3. The release of stored energy (some also pull energy storage, but not must have);4. Energy storage capacitor voltage detection;5. Interference threshold voltage detection;6.release logic. This Part 6 is the electronic control of Permanent Magnet Actuator for integral part, if any part is missing, operating agencies, under certain circumstances can not work properly. This six part, also determines the operating body can function with fluctuation resistant.
