The Bosch Rexroth MPN R911201352 (RD51.2-5B-005-L-A2-FW) is a drive control unit designed for high-voltage operation to control and monitor electric motors. It supports a 4kHz pulse frequency, a peak current of 13A for up to 60 seconds, and can handle a 200% overload for 0.5 seconds. The unit operates within a temperature range of 0°C to 40°C, requires 0.03m³/s of cooling air, and uses forced air cooling. It is configured for a 22.5mm mechanical grid allowing side-by-side mounting, and 100mm clearance is recommended above and below for airflow. Stand-by power external and starting lock-out are included as additional functions. It features a built-in brake chopper, U/f curve control line, a nominal connecting voltage of converter 3 x AC 500V (±15%), and a rated power of 5.5 kW (2.8 kW). Residual high voltage may persist for up to five minutes after shut-off due to DC link capacitors. Only manufacturer-approved cables and lines should be used; hardware modifications are not permitted.
