Designed for industrial automation, this model is capable of transforming fixed frequency voltages into more manageable, variable frequency versions. Ideal for controlling the speed of induction and synchronous motors, the R911203234 (RD51.1-5B-018-L-DF-FW) is designed to operate with a 3-phase connection of 500V, with a tolerance of ±10%. The unit contains a brake chopper to safeguard it against overvoltage situations and can effectively operate an 18 kW motor. Other key features include a 24V standby power supply module and real-time current feedback. The model works efficiently and safely within a 0 to +40-degree Celsius temperature range, with its thermal load managed by forced air cooling. To ensure optimal operation, the unit should be installed in an enclosure with adequate ventilation that meets the requirements specified by Bosch Rexroth in the RD500 series document.
