Product Description:
Bosch Rexroth Indramat is a global automation and drive technology manufacturer. The company delivers motion control products for industrial machinery and factory automation systems. It provides engineered solutions for precise control, efficient energy use, and optimized motion performance across various sectors including packaging, machine tools and manufacturing systems.
The RZW02.1-030-040 Braking Resistor is designed for dissipating regenerative energy in servo drive systems. It has a fixed resistance value of 10 ohms. The unit supports peak power dissipation up to 27 kilowatts. This peak load can be sustained for a maximum period of 48 seconds. The device operates with an operating factor of 40 % short duty (SD). It is built for temporary high energy braking scenarios in dynamic applications. The resistor is integrated into braking systems to ensure safe motor deceleration. It helps to maintain stability and protect drive components during emergency stops. The dimensions of the RZW series braking resistor are 490 mm wide, 800 mm deep, and 270 mm high. The size enables integration into control systems with sufficient space for thermal clearance. The component has been designed for intermittent use with controlled power loads. It prevents overvoltage in DC bus systems by converting excess energy into heat. Thermal durability allows operation during frequent start stop cycles. The resistor is made with durable materials that support long term use.
The RZW02.1-030-040 braking resistor is a fixed type resistor enclosed in a steel screen housing that provides both mechanical protection and efficient heat dissipation. The resistor is equipped with different terminal configurations: feature two screw type terminals for standard electrical connections while use two stud terminals in M6 or M8 sizes to support higher current capacity and ensure secure connections.
