Features
High Energy Load Resistance, small dimensions, high power, high current
Structure
HDR series Helical Coil Wound Resistors feature a high quality stainless resistor alloy wound into a long spring then wrapped onto a spirally grooved ceramic insulating core. The resistor is attached at each end of the resistor to a robust stainless steel terminal that is clamped to the core . The open-type design allows the resistor to come in direct contact with ambient air allowing it to cool more efficiently than coated resistors. The insulating core is produced from Mullite ceramics which offers excellent thermal shock resistance and sound mechanical strength.
Application
This type resistors are frequently used for light to medium duty braking of variable frequence drives, speed regulation, wye-delta starting, heating applications, elevator controls, high resistance neutral grounding and any type of AC or DC power circuit.
