High Performance Custom Magnetics for Drive SystemsReliability, Efficiency and SafetyAs global demand for natural resources increase, ONYX Power’s continued investment in R&D has provided mining as well as oil and gas industries with custom integrated power magnetics that ensure power quality through reliability, efficiency and safety. Our experienced design teams work with each customer to engineer a solution that is built to their specified physical and electrical requirements. We understand that rugged environments, demand dependable equipment and power quality. It is imperative that transformers and line reactors used in energy markets function at full performance, regardless of the environment. ONYX products are engineered to withstand unstable conditions that include:

• Extreme operating temperatures and varied geographical elevations

• Both continuous operation near rated loads as well as repeated overloads above ratings

• Loads that create high harmonic distortion

• Severe spikes and sags in load voltage current and frequency

• Mechanical and transportation vibration

• Dust, spray and contamination
