DZQⅡ-CD-101 Low voltage motor AC contactor
This product is mainly used for low-voltage motor AC contactor, frequency converter, soft starter to prevent "power swing" control, to prevent the abnormal shutdown of motor caused by instantaneous fluctuation and voltage loss of power supply, and automatic restart of important load, so as to ensure the continuity of production.
DZQⅡ-CD-101 performance
DZQⅡ-CD-101 The restart controller is developed on the basis of the traditional relay group control. It adopts modern electronic technology to synthesize the relay electronic integration product. The basic principle is the same as that of the conventional electromagnetic relay control. When the power is flickering, the built-in super capacitor is used to supply the logic circuit and the outlet relay. The analog calculation formula and the logic judgment formula are mutually locked. The voltage acquisition and processing adopts the comparison algorithm, so that the control accuracy reaches 1%.
Because of adopting DC / DC sampling technology, the influence of harmonic interference on sampling voltage is overcome. Our company pioneered the energy consumption braking speed-up technology. The response time of voltage acquisition is less than 50ms. Even if the power is shaken within 100ms, the controller can make accurate judgment and execute corresponding actions.
