RDC-3K is an intelligent programmable computer time controller with multiple parameters that can be set by users. It is suitable for time control of devices such as street lights, light boxes, garden lights, and water heaters.
The RDC-3K three‑channel intelligent time control instrument uses an industrial‑grade processor to calculate sunrise and sunset times for any location and automatically adjusts lighting schedules throughout the year. It offers three independent outputs, real‑time clock with up to ten‑year battery‑free operation, and robust protection features such as over‑voltage warning, anti‑interference up to 2000 V, and moisture resistance.
The device can be operated in automatic or manual mode. Users set on/off times for each channel via the [设置] key, adjust date, time, latitude and longitude with the cursor keys, and view real‑time status on the LCD. The manual includes wiring diagrams, parameter tables, and a troubleshooting section that guides users through power checks, contactor verification, and fuse replacement. This manual is written in Chinese.
