The Bosch Rexroth R911200205 (RD52.1-4B-011-L-V1-FW) is a converter with a built-in brake chopper designed with forced air cooling and a nominal connecting voltage of 3 x AC 380-480 V. This unit supports a rated power of 11 kW. It includes an encoder interface requiring manufacturer-specified cabling to ensure correct voltage supply. An integrated user interface allows for operation and parameterization, featuring password-secured parameter modification. The device maintains a fault memory for the 10 most recent errors and uses warning messages and a dual-color LED indicator for operational and fault statuses. Power terminals and internal relay with positively driven contacts are present, and an AL electrolytic capacitor is included as a DC link capacitor. The internal S5 jumper facilitates switching of control supply voltage.
