500W High Power Aluminum Housed Wirewound LED Load Resistors
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.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.
2.The aluminum shell is made of high-quality industrial 6063 aluminum,and the surface is high-temperature anodized to achieve attractive appearance and great heat dissipation.
Features
1.Attractive appearance & easy installation.
2.High stability,impact resistance,good reliability & high consistency.
3.Ends outgoing:metal terminals or bolted connection.
4.Inductive or Non-inductive available.
5. 25W ~ 50W used in automotive LED lamp industry; 50W, 100W & 250W used in medium frequency furnace industry.
6.Used for loading,braking,pulse,charging,discharging,starting,buffering, discharging,ect.
