Helvar EL2 2X35w sc 1-10V dimmable electronic ballast

Helvar EL2x35sc is a dimmable electronic ballast manufactured by Helvar, designed to drive two 35W neon discharge light sources. Built in steel with compact dimensions — 430 mm in length, 30 mm in width and 21 mm in depth — it fits neatly inside ceiling fixtures and luminaires for T5 fluorescent tubes. The electronic system ensures silent, flicker-free operation, offering a clear advantage over traditional magnetic ballasts.

The 1-10V dimming interface allows smooth and continuous adjustment of light output from 1% to 100%, making this ballast an excellent choice for professional lighting installations where precise light control is essential. With an input voltage range of 220–240V, it is fully compatible with standard European electrical systems. An operational lifespan of up to 50,000 hours and an energy efficiency class A1 make it a reliable, low-consumption component for technical lighting setups. The IP20 protection rating confirms its suitability for dry indoor environments.
