The ZUFK-T composite switching switch adopts advanced single-chip detection technology to achieve precise control of the relay's rapid closing at the voltage zero point and rapid disconnection at the current zero point, thereby improving the switching speed and compensation effect, and improving the anti-harmonic ability . Due to the use of magnetic latching relays, the device only consumes electricity at the moment of switching action, and does not consume electricity at ordinary times, which truly achieves the purpose of energy saving and consumption reduction. The input signal and the device have photoelectric isolation, strong anti-interference ability, safe and reliable operation.

Precautions for use
1. During transportation, the magnetic latching relay may be closed due to severe collision. If it is used directly, it may cause permanent damage to the device. The user should disconnect the capacitor bank before turning on and off the power supply ( Power on for 10 seconds), make the device in the disconnected state before the capacitor bank.
2. The input and output of the device must not be reversed, otherwise it may cause permanent damage.
3. If conditions permit, a reactor should be connected in series between the capacitor and the device.
