Power Quality Solutions in Compact Design Elspec offers compact versions of all its low voltage power quality systems—Activar, Equalizer, and Hybrid—engineered for installations with limited space. Designed in a footprint of just 120 × 102 × 76 cm, these custom-built systems deliver the same high-performance compensation for voltage drops, harmonics, and flicker, all with transient-free zero-crossing switching. Each system is modular, upgradeable, and can be configured for hybrid layouts with integrated active harmonic filtering—without compromising on performance or flexibility.
