The KSDZ-F series intelligent compound switch is the highest technical level of compound switches at present. It combines the advantages of mechanical contacts with low energy consumption and solid-state relays with no operating arc, realizes the operation of relays without arcing on and off or over-zero connection, combines the advantages of magnetic holding relays and thyristors, and guarantees the voltage over-zero closing and current over-zero separation when switching the capacitor; the switch has low surge and no overvoltage during switching, the contacts are not welded; the operating voltage and current are small, the power consumption is low, and no harmonics are generated. The product technology, performance and reliability are at the leading level in the world. It is suitable for low-voltage reactive compensation of capacitors, heating wires, lamps, motors, resistors and other loads, and is a new intelligent and environmental-friendly low-voltage switch.
