DMA 045A 4201-D

The Bosch Rexroth Indramat DMA 045A 4201-D from the DMA Servo Drive Modules series delivers robust three-phase drive performance and includes an integrated gear encoder for precise feedback. This inverter module is designed for connection to high or medium voltage systems via a transformer and must not be directly connected to a public low-voltage power supply. It features a 24 VDC current input of 1.32 A for control circuitry and accepts a main input voltage of 670 V to generate a stable output voltage of 400 V. A powerful non-regulated DC link voltage of 715 VDC ensures rapid energy exchange and dynamic response for demanding servo applications.

Installation and environmental resilience are engineered into every unit. The drive stands 521 mm in height and installs inside switch cabinets compliant with IP54 protection standards to guard against dust and water ingress. It operates across a wide storage temperature range of -25 °C to +70 °C and adheres to climatic category 3K3 under EN 60 721, ensuring reliable performance in humid, dusty, or corrosive atmospheres. Thermal management is optimized to limit a maximum power loss of 220 W, while mechanical ruggedness provides 15 g shock resistance (DIN IEC 68-2-27) with no functional disturbance. Vibration displacement remains below 1 mm at 2 Hz to 13.2 Hz to maintain sensor and component integrity.

Field operation extends up to 1,000 m above sea level at rated data, with automatic derating between 1,001 m and 3,000 m to preserve thermal limits and drive life. The inverter may cause radio interference outside industrial zones, so appropriate countermeasures are recommended in residential areas. All units carry a one-year warranty and can be shipped globally, making the DMA 045A 4201-D an adaptable solution for machine builders requiring precision, protection, and worldwide support.
