Product Description

The Rockwell Automation 1756-PBR2K, also known as the Allen-Bradley 1756-PBR2K, is a PowerFlex 7000 Braking Resistor module designed to manage regenerative energy in AC drive systems. It is compatible with PowerFlex 7000 drives, offering robust performance in high-power industrial applications such as motor control, material handling, and heavy machinery. This module operates within a voltage range of 380-690V AC and supports three-phase input configurations. It features a high-capacity thermal design with a power rating up to 75 kW, ensuring efficient energy dissipation under dynamic braking conditions. The 1756-PBR2K integrates seamlessly into ControlLogix systems via direct backplane connectivity, eliminating the need for external cabling. Its compact, rugged enclosure is built for harsh environments, with an operating temperature range of -25°C to 40°C. Key advantages include reliable overload protection, simplified installation, and compatibility with multiple drive configurations, though it requires adequate ventilation for optimal performance. Ideal for industries like mining, steel, and energy, this braking resistor ensures system stability by preventing DC bus overvoltage during deceleration cycles.
