Description
The ACS-BRK-D is a brake chopper manufactured by ABB, a company specializing in power and automation technologies. Here’s a breakdown of the product information:
Product Name:
- ABB ACS-BRK-D Brake Chopper
Product Description:
The ACS-BRK-D is a device designed to dissipate the energy stored in the motor’s rotating inertia during deceleration or braking. It’s commonly used in conjunction with ABB’s variable speed drives (VSDs) or drives from other manufacturers.
Product Functionalities:
- Prevents Overvoltage: When a motor brakes or decelerates, it generates electrical energy that can feed back to the drive. The brake chopper safely dissipates this excess energy as heat, preventing damage to the drive and ensuring smooth braking.
- Extends Braking Time: By absorbing the regenerated energy, the brake chopper allows for longer braking times compared to relying solely on the motor’s friction. This is crucial for applications requiring precise stopping control.
- Reduced Wear and Tear: By handling the braking energy, the brake chopper reduces wear and tear on the motor’s mechanical braking system (if applicable).
Product Parameters and Specifications (Refer to ABB Datasheet for details):
- Input Voltage: The voltage range the brake chopper can accept from the drive (e.g., 220V AC, 400V AC).
- Braking Power: The maximum power the brake chopper can dissipate as heat (e.g., 7 kW continuous, 42 kW for 20 seconds).
- Braking Resistance: The internal resistance value within the brake chopper responsible for heat dissipation. Some models might allow connecting an external resistor for increased braking power.
- Control Interface: The method of communication between the brake chopper and the drive (e.g., digital signals).
- Environmental Ratings: The operating temperature range, humidity tolerance, and vibration resistance for reliable operation in industrial environments.
