Functions

Benefit

-Save electric power consumption by dimming -Healthy ROI by minimized investment

-Dimming Rate : over 40%

-Cluster : Up to 40 lamps -Controller : Interface to LAN is available

-Decreased electric power consumption / Minimum investment / Extended useful life / Less EMI

Technical Approach -Adoption of MERS Controller on conventional fluorescent lamp system

-Improved steel ballast if necessary -Cluster dimming control of lamps

Electronic PWM (Dimmable) Ballast(Dimmable) MERS + Magnetic Magnetic Ballast (Not dimmable)

lifecycle cost

useful life

switching loss high very low or nothing

3 to 5 years 10 years and more very high very low - 60% less than electric in 10yrs

lighting efficiency 20% and more not improved

wiring 2+3 wire 2 wire only

initial cost very high low - can use magnetic ballast

MERS Controller specification (tentative)

recommended Ballast Magnetic steel ballast, rapid or preheat type Electronic ballast is not applicable Operating voltage AC90V up to 240V 50Hz/60Hz, DC not permitted 100V or 200V mode jumper-pin

MERS capacitor 5uF to 40uF film capacitor according to load inductance Parallel connection units Not limited, same electric characteristics are

required in the same MERS segment

for stable dimming

Fuse protection 20A

Operating temperature +5degC to +40degC (+41degF to +104degF)

Operating humidity 25% to 80%RH

Protection mode Overheat, capacitor over voltage, current overload

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
