Product Overview

RXLG series aluminum case wound resistor adopts aluminum alloy case with beautiful appearance. The resistor has weather resistance, vibration resistance and safety superior to traditional ceramic skeleton resistor. RXLG resistor is a kind of high temperature resistant silicone resin and silicon powder as the basic material package of power wound resistor.

■ Product application

As a braking resistor, the inverter, servo, etc. are protected from the harm of the regenerative electric energy of the motor

As resistive load in power electronic load test

As sampling resistance, current limiting resistance, starting resistance and protection resistance in power electronic equipment
