HEW_™ Single
Phase AC/DC Reactors: A Recommended Alternative

MPS Industries, Inc. introduces our HEW (Helical Edge Wound) Single Phase AC/DC Reactors, customized and optimized for your specific reactor needs. These reactors are a recommended alternative for amorphous/lamination core and copper foil wound reactors.

Highlights and Advantages to this Alternate Design Approach:

• Designed with distributed gap powder cores = minimum gap loss
• No concentrated hot spot on the winding due to fringing flux from the gap
• Soft saturation
• Low audible noise level

• Clean single layer HEW winding
• Single layer winding = better heat dissipation
• Machine-wound = less labor intensive, more cost effective
• Lower losses (for AC), proximity effect, and capacitance vs. copper foil counterpart
