The 20AD-DB1-A is a component from the PowerFlex 70 product line by Allen Bradley, specifically an internal dynamic brake resistor. This device has a small duty rating and is engineered to mount directly on the back of the PowerFlex 70 drive, enhancing installation convenience. Notably, there is no requirement for an external safety circuit to protect against resistor overheating during operation.

This brake resistor is designed to accommodate a variety of PowerFlex 70 drive voltage ratings, including 400-480V AC and 500-600V AC. With a resistance of 115 Ohms, it effectively manages power and braking systems. It supports a continuous power rating of 0.048 kW, ensuring reliable performance for applications that demand effective braking.

The brake resistor is compatible with Frame Size A of PowerFlex drives, allowing for streamlined integration. For 400-480V AC drives, it can work with normal duty horsepower ratings of 0.5 HP, 1 HP, or 2 HP. Similarly, it offers compatibility for the same horsepower ratings when connected to 500-600V AC drives. This versatility enhances seamless adaptability in different configurations within the PowerFlex drive system.
