WattStopper RT-200-A Astronomical Time Switches

Description:

The WattStopper RT-200-A is an astronomical time switch designed to automatically control lighting and electrical loads based on programmable schedules, sunrise/sunset calculations, and time-of-day settings. The device replaces a standard wall switch and features a digital OLED display, manual override capability, and multiple programmable events for energy-efficient operation. By using location-based astronomical calculations, the RT-200-A automatically adjusts switching times throughout the year to match seasonal sunrise and sunset changes, making it ideal for lighting control, security applications, and energy management systems.

Applications:

The WattStopper RT-200-A is commonly used in commercial buildings, office facilities, schools, retail stores, healthcare institutions, government buildings, warehouses, exterior lighting systems, security lighting installations, parking areas, signage control systems, and energy management applications where automated scheduling, astronomical lighting control, load switching, and energy conservation are required to improve operational efficiency and reduce energy costs.
