DCES Only for Variable-frequency Drive Protection

DCES is a multifunctional electrical safety active defense device designed for low-voltage frequency converters, including voltage short-term interruption support and voltage sag regulation. It can seamlessly address issues such as voltage fluctuations and voltage short-term interruptions in real-time.
DCES uses supercapacitors for energy storage, outputs DC DC power, and connects to the frequency converter as a backup power source. Completely isolated from the frequency converter during normal operation. When the fluctuation value of the power grid voltage does not reach the set value, the system does not work and is in a hot standby state; When the voltage fluctuates within the protection zone, DCES starts working to ensure the normal operation of the frequency converter; When the voltage of the power grid is restored, DCES automatically exits the working state and switches to the hot standby state, and the frequency converter automatically switches to be powered by the power grid; When the external interlocking input action or the frequency converter stops running, the device automatically exits and switches to the hot standby state.
