120W 500R Aluminum Clad Led Load Braking Resistors For Elevator
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.
3.Used for loading,braking,pulse,charging,discharging,starting,buffering, discharging,ect.
Features
1.We supply standard and custom designed aluminium housed resistors for general-purpose use,power supplies, power generation and the traction industry.
2.The RH is a range of extremely stable, high quality wire-wound resistors capable of dissipating high power in a limited space with relatively low surface temperature.
3.The power is rapidly dissipated as heat through the aluminium housing to a specified heatsink.
4.The resistors are made from quality materials for optimum reliability and stability.
5.We can test resistors to conform to relevant international or customer specifications.
6.We are happy to advise on the use of resistors for pulse applications and to supply information for high voltage use and low-ohmic value,alternative mountings and termination type.
