Features
HDB series high power resistance, small volume, low inductance, strong impact resistance, high stability, suitable for low resistance and high current situation, power range: 500W ~ 3KW
Structure
HDB edgewound resistors are lightweight, heavy-duty units consisting of a non-corrodible, high quality stainless steel alloy. The ribbon-like is wound on edge in the form of a helix, and then spun onto a ceramic core. Type ER resistors are supported by a threaded rod passing through the center of the ceramic core. Type ERB resistors are supported by a mounting bar which is slotted at either end. Fixed terminations are made by welding stainless steel tabs to either end of the , or at various points for multiple connections. This unit includes fixed terminals, through-rods, through-bars, hardware and stain-less steel .
Application
Edgewound resistor commonly used for VFD braking, motor control, load banks and neutral grounding applications. are suitable for continuous duty applications where low resistance and high current are required. The high mass allows these units to withstand high current, intermittent duty applications. This characteristic, combined with the high-temperature ceramic insulation, makes the edgewound ideal for neutral grounding applications, which reach temperatures as high as 800°C.
