ULTRA-K Series 600K-he Three Phase
A high-efficiency, K-rated power conditioning transformer engineered to protect sensitive electronic loads while reducing operating costs.
The ULTRA-K Series 600K-he Three Phase (15 kVA – 500 kVA) is a high-efficiency, K-rated power conditioning transformer engineered to protect sensitive electronic loads while reducing operating costs. Exceeding DOE 2016 efficiency standards, it delivers superior noise attenuation and transient voltage suppression to safeguard mission-critical systems. With multiple K-factor ratings (K4, K7, K13, K20), it handles harmonic-rich, non-linear loads common in today’s environments. Durable copper-wound construction and flexible voltage/output options make it ideal for data centers, healthcare, education, retail, and industrial facilities requiring reliable, clean power.
