RR52.1-7N-004-P-V1-FW

The Bosch Rexroth Indramat RR52.1-7N-004-P-V1-FW from the RD 500 Drive Controllers series is a robust DC supply inverter designed to operate with a motor output of 3.0 kW and an output frequency range of 0–500 Hz. This device features a specialized heat conducting plate cooling mode and is classified as an inverter without a built-in brake chopper. It accepts a DC 650 V supply with a tolerance of ±10 % and meets A1 class radio interference limits. Engineered for textile and general automation, the RR52.1 ensures precise speed control over the full 0–500 Hz span.

Reliability is reinforced by its IP20 degree of protection and 3K3 environmental class, which safeguard internal electronics against dust and moisture. The module delivers a continuous output of 6.6 kVA at a rated current of 9 A, while sustaining peak outputs up to 8.6 kVA for 60 seconds without derating. Natural or forced convection—through filtered, dust-free air—maintains thermal stability under cyclic loads. The device’s tolerance to short overvoltage or overcurrent events (0.5–60 seconds) further extends operational resilience in demanding industrial environments.

Weighing just 10 kg and featuring a compact form factor, the RR52.1-7N-004-P-V1-FW is ideal for installations with limited panel space. A built-in display simplifies diagnostics, parameterization, and maintenance, reducing commissioning times. Overall, this inverter offers a balanced combination of 3.0 kW power, flexible 0–500 Hz frequency control, and streamlined cooling, making it a dependable choice for modern automated drives.
