The EAK series of high-power resistors are designed for applications in power generation, power transmission, variable-speed drives, and other electrical equipment fields. These resistors are optimized for high-power dissipation and robust performance under demanding conditions.
Technical Features
Base Plate Temperature : ≤ 85°C.
Rated Power : Available in 300W, 600W, and 800W ratings.
Special Design : The resistor features a compact structure with chip-to-case bonding using spring terminals. It is secured with two M4 screws to ensure a clamping force between 120N and 160N.
Material Compliance : Passes UL94 V0 flammability standards.
Application Case: Variable-Speed Drive System
Background
In industrial applications, variable-speed drive systems require precise control of motor speed and torque. High-power resistors are often used as braking resistors to dissipate excess energy during deceleration, ensuring smooth operation and preventing damage to the system.
Solution
- Resistor Selection : Choose an EAK series resistor with a rated power of 600W at 85°C. This ensures sufficient power handling capacity for the braking application.
- Installation : Mount the resistor using M4 screws with a maximum torque of 1.8Nm to ensure secure installation and proper heat dissipation.
- Thermal Management : Monitor the base plate temperature to stay below 85°C. Use forced air cooling if necessary to maintain optimal operating conditions.
- Safety Considerations : Ensure compliance with UL94 V0 standards to prevent fire hazards in industrial environments.
