Engineered for performance, safety, and long-term reliability, the EL432-120/277HF Electronic Ballast is a high-efficiency lighting solution designed for demanding commercial and industrial lighting systems. Built with solid-state electronic architecture, this ballast supports parallel lamp operation for a range of T8 fluorescent lamps and delivers consistent, flicker-free illumination with high power factor and sound-rated Class A operation.

This universal voltage model is rated for 120V to 277V input, making it suitable for a wide variety of applications across multiple voltage environments. The ballast supports 3 or 4-lamp configurations, compatible with lamp types including F17T8, F21T8, F25T8, F32T8, F36T8 (TLD36W), and even 2 or 3 F40T8 lamps—ensuring flexibility across both retrofit and new lighting installations.

Featuring inherent thermal protection, the EL432-120/277HF is date-coded for traceability, constructed with aluminum housing, and includes a full set of color-coded solid 18AWG wire leads in multiple lengths for easy wiring during installation. It operates at high frequency to improve lamp efficacy and visual comfort while minimizing audible noise and harmonic distortion.
