ULTRA-K Series 600K-he Single Phase

The ULTRA-K Series 600K-he Single Phase  (5 kVA – 25 kVA ) is a high-efficiency, K-rated power conditioning transformer engineered to protect sensitive electronic loads while lowering operating costs. Designed to exceed DOE 2016 minimum efficiency standards, it delivers superior electrical noise attenuation and transient voltage suppression, ensuring clean, reliable power for mission-critical systems. With multiple K-factor ratings (K4, K7, K13, K20), the ULTRA-K safely handles harmonic currents from non-linear loads, extending the life of LED drivers, ballasts, and electronic equipment. Durable copper-wound construction, optional surge protection, and versatile enclosure choices make it a long-lasting, adaptable solution for industrial and commercial applications.
