Integration with Smart Facility Manager
Lighting Controller
1. Dimming control of fluorescent lamps, mercury lamps and metal halide lamps.
• More than 40% electric power saving compared with NO MERS systems.
2. Replace mercury lamp with metal halide lamp with MERS metal halide controller.
• Approx. 40% electric power saving compared with NO MERS mercury lamp systems.
(from Titech experiment)
3. Intelligent dimming control of lamps with MERS, sensors and Constraint Technology.
• Significant saving can be expected compared with existing systems according to QOS.
