Description
Reviews

The Vossloh‑Schwabe VS Choke Driver Ballast is a rugged, precision-engineered magnetic ballast ideal for high-power HPS or Metal Halide flood lighting. Built with copper-wound transformers, resin potting, and thermal reset protection, it delivers stable lamp performance, high efficiency, and long service life in demanding outdoor installations.

Features & Functions
Magnetic ballast (choke) design engineered for high-pressure discharge lamps (HPS and Metal Halide), typically in the 100 W to 400 W range.
100% copper winding transformer, potted in fire-retardant polyester resin for durability and thermal stability.
Integrated thermal protection with automatic reset, safeguarding against overheating and ensuring operational reliability.
Highly consistent impedance tolerance, enabling stable lamp current and optimizing both luminous output and lamp lifespan.
Energy-efficient classification, achieving A2 rating with under 36 W power dissipation in non-dimmable configurations
