SGDH series 200-350Amp capacitor Implement Switching private solid state relay Manual
The SGDH series solid‑state relays are single‑pole‑single‑throw (normally‑open) devices designed for capacitor switching in reactive power compensation equipment. They feature a DC control input, high‑reverse‑voltage SCR parallel structure, and a "zero‑voltage‑difference" conduction method that reduces surge and arc currents during capacitor insertion and removal.
The relays are built with German‑imported high‑reverse‑voltage SCR chips and vacuum‑welded construction, offering high dV/dt and dI/dt capability, up to 1600 V blocking voltage, and rated currents of 200 A, 250 A, or 300 A. Recommended installation includes a suitable heat sink, fast‑acting semiconductor fuse, and thermal grease between the device and heat sink. This manual is written in Chinese.
