Helvar EL2 2X49w sc 1-10V dimmable electronic ballast

Helvar EL2 2X49W sc is a dimmable electronic ballast manufactured by Helvar, designed to drive two neon discharge light sources of the T5 type, rated at 49W each. Built in steel, it features compact dimensions — 430 mm in length, 30 mm in width and 21 mm in depth — making it easy to integrate within fluorescent luminaires and ceiling light fixtures. The control protocol adopted is the 1-10V system, which enables smooth and precise dimming of the light output.

Thanks to its compatibility with the 1-10 Volt dimming system, this electronic ballast allows continuous adjustment of light intensity across a full range from 1% to 100%, ensuring optimal lighting control in environments that demand flexibility and energy efficiency. The input voltage ranges from 220 to 240V, fully compatible with standard European electrical systems. The IP20 protection rating makes it suitable for installation in protected indoor environments. The A1 energy efficiency class certifies the outstanding performance of this component in terms of energy consumption, while the estimated lifetime of up to 50,000 hours ensures long-term reliability.
