Product Description

The DMA 030A 7301-D is a three-phase module. It is part of Servodyn-D series from Bosch. The module is designed for control of synchronous / asynchronous motors. At 2 kilohertz switching frequency, the rated output of the DMA 030A 7301-D is 30 Amps. At 4 kilohertz switching frequency, the maximum and rated current values are 35 Amps and 13 Amps for peak overload conditions. At 8 kilohertz switching frequency, the maximum and rated current values are 32 Amps and 5.1 Amps for peak overload conditions. At 4 kilohertz switching frequency, the maximum and rated current values are 28 Amps and 18 Amps for peak continuous load conditions. At 8 kilohertz switching frequency, the maximum and rated current values are 23 Amps and 12 Amps for peak continuous load conditions.

The regulated DC link voltage for the DMA 030A 7301-D is 670 Volts DC. The unregulated DC link voltage for the module is 715 Volts DC. Bosch has recommended optimal ambient conditions for operating the DMA 030A 7301-D module. These recommendations include peak altitude of 1000 meters or less and 32 to 113 degrees Fahrenheit temperature. The module output derates at temperatures that exceed 113 degrees Fahrenheit and at altitudes that exceed 1000 meters above mean sea level. Operation of the DMA 030A 7301-D module at temperatures exceeding 131 degrees Fahrenheit is not recommended. Storage temperature range for the three-phase module is -13 to 158 degrees Fahrenheit. Weight of the module is 50 millimeters and its height is 520 millimeters. The module supports a CANrho interface and resolver based feedaback. Installation, commissioning and operation of the DMA 030A 7301-D should only be performed by suitably qualified personnel. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
