The dimmable light and control method has been improved with the electronic ballasts technology constantly innovating and developing. With the high frequency electronic ballasts being invented in recent year, the technological performance of ballasts had been changed, and there are lots of high efficiency, excellent performance, wide dimmable range, high frequency intelligentized dimmable electronic fluorescent lamps ballasts had been gradually launched. Those ballasts have become main dimmable control products for fluorescent lamps ECG (electronic control device).

Dimmable electronic ballasts control line can be divided into “two line system” and “four line system” “Four line system” dimmable electronic ballasts have been widely used currently, in which the power is supported by dimmable controller through two of electrical source lines. Two low voltage control line and interface dimmable ballasts fulfill switch, dimmable and various functional controls.

EASEIC Dimmable Electronic Ballast series with four-line system, providing 0/1-10V analog dimming control interface. The representative of the series is universal voltage dimmable electronic ballast for fluorescent lamps.

* Universal input voltage (120-277VAC)

* High power factor(λ>0.98*)
* Standard DC0/1-10V control interface
* Dimming range from 1-100%
* Lamp start at 1% possible
* Defined Lamp friendly warm start within 1.5 s with AC and 0.6s with DC
* High luminous efficacy
* Virtually eliminates lamp flicker
* Safe shutdown of defective lamps
* Safe shutdown of lamps at end of life
* Automatic restart after lamp replacement
* Operating frequency ~40-120kHz
* Operating temperature(ta = -20→+50℃)

With great efforts that EASEIC had been making for many years, EASEIC is leading in the field and has offered approximate hundred specifications of digital dimmable electronic ballasts based on 0/1-10V analog signals dimmable control interface and DALI addressable interface, which apply to large-scale conference room, exhibition hall, studio, theaters and outdoor night scenery lighting and various important situations.

The combination for Fluorescent lamps dimmable ballast and controller
The complete set use of fluorescent dimmable ballast special dimmer and illumination (movement) sensor and dimmable ballasts make the combination of illumination compensation, movement detection and manual adjusting light for small conference room, classroom, office, which meet the multi-needs while effectively saving energy sources. At present, there are lots of lighting control systems and intellectualized lighting control systems, such as EIB, C-bus, A-bus, CAN-bus, DYnet and etc offer 0/1-10V analog signals dimmable control interfaces. Those control system can make the lighting of the whole multi-storied building being centrally controlled, and fulfill fixing point loop switch and dimmable control through intelligentizing, which are applicable to situations needed being large-scale controlled.
