SDH Constant Current Integrated Unit/Controller Installation Manual
The SDH series combines solar, AC charging, LED constant‑current output and intelligent control in a single unit. It can charge batteries from both solar panels and mains power, manage power distribution, and protect against over‑voltage, under‑voltage, and overload conditions. The integrated unit also supports infrared human detection, voice control, remote communication, and six programmable load‑power time slots.
The controller version removes the constant‑current module, allowing direct power supply to loads such as motors or DC constant‑current sources. The manual provides step‑by‑step wiring, indicator‑light meanings, safety precautions, and common fault‑handling procedures to ensure reliable operation in temperatures from –35 °C to 55 °C. This manual is written in Chinese.
