Aluminium Enclosed Resistor Type CJT Series Key Features Modular versions available Environmental protection to IP54 Up to 2000W power rating Aluminium enclosure Vibration resistant Applications Power supplies Inverters Servo systems Electrical systems in difficult environments TE Connectivity (TE) is a leading supplier of standard and custom-designed power resistors for industrial, control and general-purpose applications. The CJT Series of resistors are advantageous to conventional ceramic resistors in the terms of weather proofing, oscillation-resistance and safety. They are widely applied to a range of electrical circuits including power supplies, inverters and servo systems. With easy airtight fitting and the ability to fit a heatsink the resistor is highly suited to challenging environmental conditions.
