Aluminum housed Resistor Multi Unit 20kw
The ARXU series resistors with optional integrated thermal switch from our medium power range of ALUMINIUM HOUSED COMPACT BRAKE RESISTORS are electrically insulated and with small dimensions to be fitted into compact constructions. They are jointed two or more aluminum resistors in paralle or in series to obtain required high power and resistance.This series are adding stainless plate shields and stands at the tow ends of traditional aluminum enclosure resistors in order to seal resistor properly.
1.High IP class of IP00，IP21，IP33 or as required;
2.High pulse load and high vibration capability;
3.Compact structure,and cool surface;
4.No live parts outside;
5.Low noise level;
6.Low thermal drift;
7.Terminals suitable for soldering or bolt connection with high temperature.
