RZW02.1-090-015
RZW Braking Resistors
The Bosch Rexroth Indramat RZW02.1-090-015 from the RZW Braking Resistors series delivers a robust power rating of 90 kW and operates with an Operating Factor of 15% SD to manage dynamic braking energy. This Type Of Resistor F2 unit features a Resistance of 2.5 Ω and supports a Min Connectable Resistance of 30 Ω for versatile system integration. Designed to withstand industrial automation demands, it incorporates a Thermal Time Constant of 100 s to ensure predictable heat dissipation. Compact and durable, this resistor leverages standard interfaces for seamless installation.
Engineered for reliable thermal management, the RZW02.1-090-015 includes a Built-in Ventilator Specification of 3 AC/400 V/50 Hz/3.5 kVA that actively cools the resistor element under heavy loads. The ventilator’s design aligns with a Cross-section For Conductor of 50 mm² and integrates External Ventilation Components with air current monitoring and wind vane relay to prevent performance loss. Rated for an Environmental Temperature Range of 0°C to 40°C and a Humid Environment Restriction of ≤90% (non-condensing), it maintains consistent operation in diverse plant conditions. The combination of active cooling and protective monitoring maximizes uptime while reducing thermal stress on connected drives.
Safety and system compatibility are enhanced by an IP20 Protection Class enclosure that shields the resistor from accidental contact and debris. For short-term overloads, the unit delivers a Peak Power At 6% SD of 67 kW, while maintaining defined cycle times of 48 s on/72 s off at 40% SD and 72 s on/48 s off at 60% SD. These specifications ensure the braking resistor can absorb and dissipate regenerative energy during rapid deceleration, safeguarding drive electronics and mechanical components.
