RD41.1-6B-025-L

The Bosch Rexroth Indramat RD41.1-6B-025-L from the RD 500 Drive Controllers series delivers a 25 kW rated output at 3-phase AC 400 V and sustains a 50 A rated current in a modular power supply module. Manufactured by Bosch Rexroth Indramat, this device variant is equipped with a brake chopper and an integrated braking resistor to manage regenerative energy in the DC link. Its three-phase 400 V AC supply voltage features a tolerance of ±15%, ensuring compatibility with fluctuating mains conditions. The module’s compact footprint and touch-proof IP20 protection degree make it ideal for industrial cabinets where space and safety are priorities.

Engineered for robust operation, the RD41.1-6B-025-L complies with environmental class 3K3 per DIN IEC 721-3-3, allowing an ambient temperature range of 0 °C to 40 °C and a relative humidity up to 95% (absolute humidity up to 29 g/m³). The forced air cooling system maintains optimal internal temperatures during continuous operation and under peak loads. An in-built braking chopper engages automatically when DC-link voltage thresholds are reached, diverting excess energy into the braking resistor to prevent overvoltage. Maintenance is simplified by straightforward access to the cooling fan and chopper assembly, reducing mean time to repair in high-throughput applications.

Ideal for machine tools, conveyor systems, hoists, and packaging machinery, the RD41.1-6B-025-L integrates seamlessly with other RD 500 modules and Bosch Rexroth drive control units. Its precise voltage regulation and regenerative capability support energy-efficient operation and drive safety functions such as overload shutdown and fault diagnostics. Whether deployed in chemical processing or food-industry automation, this power supply module offers reliable performance and simplified commissioning in demanding industrial environments.
