Product Description

200W 75ohm Aluminum Shell Resistor RXLG Used For Servo Brake Resistor

 

The 200W aluminum shell resistor is a high-power resistor made of high-quality aluminum alloy material. It uses an aluminum shell as the outer shell and combines a special process design to effectively solve the problems of high power dissipation and heat dissipation, ensuring good performance even in a long-term working environment. This product is widely used in industrial equipment, control systems, power transformers, automation equipment, testing instruments and other fields

 

Heat dissipation performance of resistors
The aluminum alloy shell itself has excellent thermal conductivity. Combined with the design of the heat sink and the optimized structural layout, the heat dissipation efficiency is significantly improved. Compared with traditional ceramic or metal resistors, aluminum shell resistors can dissipate heat more quickly under high-power loads, reduce temperature rise and extend the service life of equipment.

 

The heat dissipation advantages of aluminum shell resistors

The metal casing has good thermal conductivity.

It is designed with heat dissipation grooves.

Suitable for high-power application scenarios.

 

The characteristics of porcelain tube resistors

Ceramic material is resistant to high temperatures.

It has a simple structure and low cost.

Suitable for low-power environments.

Good insulation performance.
