1000W 100R Aluminum Cased Power Dynamic Braking Resistance for Converter break resistor
Structure :
1.The resistors core components are made of insulating and high-temperature resistant materials as the resistors framework,evenly wound with high-quality alloy wires.
2.Metal aluminum shell potted with high insulation non-combustible electronic paste,so that the aluminum shell and the resistance core components are closely combined into a solid entity,not affected by external air,vibration and dust,high stability and thermal conductivity.
3.ZENITHSUN series including ASZ(trapezium shape),ASC (ship shape)and ASCB(ultrathin shape),the mould can get more than 20 species to let resistors suit for environment installation and application.ASZ successfully applied for the national patent.
4.Aluminum resistor is also called braking resistor or charge resistor or bleeder resistor or current-limited resistor or ageing resistor or load resistor.
5.Resistance to shock,strength power ,fast dissipation heat ,high stability,long life.Aluminum resistor is one of core products of ZENITHSUN.
6.ZENITHSUN is the most complete varieties and most powerful production aluminum resistors of manufacturer in Pearl River Delta,and even in the whole country of China.
Features
1.Internal wire wound resistor is protected by external Aluminum Case from external mechanical force,humidity and dusty.
2.Suitable for industrial machinery and equipment,electric power distribution.
3.Durable and can withstand stronger vibration.
4.Low temperature coefficient and better heat conduction.
5.Support Low Inductance requirement.
6.Precision Resistance Tolerance +/-0.1%, +/-0.5%, +/-1% ,+/-5% ,+/-10%.
