Product Overview: The DCM621KH motor shock protection device (also known as a shock protection module) is a product designed to ensure that contactors release automatically during power grid fluctuations, thereby preventing the motor from stopping. It operates in parallel with the control circuit and is primarily used for protecting direct-start motors, frequency converters, and soft-start motors against power shocks. The anti-vibration power module boasts many advantages, such as accurate operating condition recognition, high reliability, and simple operation and maintenance. The DCM621KH contactor restart anti-vibration device, as a new type of anti-vibration apparatus, generates a composite judgment criterion by collecting data on the operating power supply, the voltage of the contactor coil, and the voltage in the control circuit. After startup, it enters anti-vibration standby mode after a 5-second delay; when there is a change in the contactor’s position signal, the internal supercapacitor system activates automatically, and the system begins timing. If power supply is restored automatically within the set maximum vibration time, the motor is started after another delay period, thereby restoring normal operation prior to the occurrence of vibrations and ensuring uninterrupted production. The voltage fluctuation resistance modules for frequency converters and soft starters require the reset and restart of the frequency converter or soft starter, and they need to work in conjunction with the DCS system. Voltage fluctuation protection devices can be widely used in industries such as petrochemicals, metallurgy, paper manufacturing, and food processing. Main features of the product: ☆ The starter motor automatically goes into standby mode; manual shutdown triggers automatic discharge. ☆ Magnetic installation, reliable and flexible. ☆ Plug-in terminals for easy maintenance. ☆ No shock restarts, ensuring stable power grids for motors. ☆ The flicker time can be as long as 9 seconds, and it is easy to modify. ☆ The restart delay can be modified, which is beneficial for multi-motor environments in batches. ☆ Voltage fluctuations did not cause the contactor to release, and they have no effect on the surge suppression module.
