2000W 150 Ohm J High Power Wirewound Damping Ressistors for Servo
Structure
1.High Power,Small Size & Fast Heat Dissipation,multi-tap and non-inductive winding are available.
2.Can be combined to be arranged in the load banks.
3.Our high power resistor personalized design to better meet your requests,so as to greatly save space and cost.
Features
1.The product has the characteristic with solid structure,small volume and high power.
2.It is an ideal product in high impact and long-term load environment & also be applied to the solution of load banks.
3.The resistance wire of high power resistors select iron chromium aluminum, nickel chromium wire or constantan wire with high temperature resistance, stable electrical performance and small temperature drift coefficient.
4.HDR,HDB and DHZ spring shape high-power resistors are made of high-temperature resistant ceramic tube as the matrix,the resistance wire is processed into a spring shape and wound in a fixed wire slot,and the leading out is stainless steel end piece.
