RD52.1-8N-110-L-V1-FW

The RD52.1-8N-110-L-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers DC supply inverter delivers 110 kW of continuous power and accepts a DC 700 V nominal input. The unit is specified as an inverter without a built-in brake chopper and utilizes a forced air cooling mechanism for thermal management. Its compact size class E chassis supports vertical mounting inside industrial control cabinets under an IP20 protection rating. This robust construction ensures long-term performance in challenging electrical environments.

Performance at a 4 kHz carrier frequency provides a 90 kW rated motor output across 0–250 Hz, with a 160 A rated current, 208 A for 60 s, 272 A for 1 s, and 320 A for 0.5 s, yielding 132 kVA continuous and 171 kVA peak for one minute. When operated at 6 kHz, the inverter extends output to 0–500 Hz with 130 A rated current, 169 A for 60 s, 221 A for 1 s, and 260 A for 0.5 s, delivering 107 kVA continuous and 139 kVA peak for one minute. The device derates at 2.5% per K between 40 °C and 50 °C and operates safely within a permitted ambient range of 0–40 °C. It also incorporates an optional 24 V standby supply to maintain control electronics when main DC power is removed.

With its sturdy IP20 housing and efficient airflow path, the RD52.1-8N-110-L-V1-FW integrates seamlessly into automated production lines and complex machine tool cells. Commissioning and maintenance are streamlined for qualified personnel, leveraging the standby power feature for uninterrupted parameter configuration and rapid diagnostics. Shipped globally with a one-year warranty, this drive controller delivers reliable operation and simplified deployment across diverse industrial applications.
