长和CH09-B六路经纬时控仪是一款智能型时控设备，广泛应用于城市路灯、工厂车间、广场、隧道、车站等场所的照明控制。它采用高精度实时时钟作为计时基准，无需外接电池，计时准确，每月误差不超过1秒。该设备具有强大的自适应功能，用户只需一次性设置好当地经纬度、日期、当前时间及开关灯时间，设备便能根据季节变化自动修正开关灯时间，确保每天开关灯时间合理，无需频繁调整。此外，CH09-B还具备手动与自动互换功能，用户可根据需要选择手动操作或自动控制。其控制功率为AC220V/10A×3，适用于多种负载。

The Changhe CH09-B six-channel longitude and latitude time controller is an intelligent time control device, widely used in urban street lighting, factory workshops, squares, tunnels, stations, and other places for lighting control. It uses a high-precision real-time clock as the timing benchmark, without the need for external batteries, and the timing is accurate, with an error of no more than 1 second per month. The device has a strong adaptive function. Users only need to set the local longitude and latitude, date, current time, and switch-on and switch-off times once, and the device can automatically correct the switch-on and switch-off times according to seasonal changes, ensuring that the switch-on and switch-off times are reasonable every day, without the need for frequent adjustments. In addition, the CH09-B also has a manual and automatic switching function, and users can choose manual operation or automatic control according to their needs. Its control power is AC220V/10A×3, suitable for a variety of loads.
