Product Description

High Power Circular Edge-wound resistor (REWR-R Series)

 

            








 

 Product Characteristics                                                        

The resistance body is made of stable resistance alloy.  The ribbon element is wound on edge in the form of a helix, and spun onto a ceramic bracket . The continuous surface temperature does not exceed 375ºC. REWR-G  series can be used for any AC or DC power application. Units are most commonly in VFD braking , motor control, load banks and neutral grounding and etc.

Product size and value can be designed according to customer requirements, or assembled into components.
