DMA 85B 7301-D

Product Description

The Bosch DMA 85B 7301-D is a Servodyn-D three-phase module for synchronous / asynchronous motors. Servodyn-D systems are fully digital inverter systems. They can be used with SF, SR and other synchronous motors with absolute length measuring system. Servodyn-D systems can also be used with DU and other asynchronous motors with absolute encoder or gear encoder. Servodyn-D systems are available as either standalone inverters or as module inverters. The DMA 85B 7301-D is a module which can be used in a modular Servodyn-D inverter. The DMA 85B 7301-D is an air cooled device. Width of the module is 100 millimeters and its height is 521 millimeters. The inverter module can be plugged into the backplane module. Interface available on the DMA 85B 7301-D is CANrho. Encoder interface is also available on the module for resolver. Maximum current rating of the module is 85 Amps.

The module supports integrated DC link connection. The DC link voltage is 670 Volts DC for regulated operation and 715 Volts DC for un-regulated operation. Weight of the DMA 85B 7301-D is 11.5 kilograms. The rated maximum power loss for an operating DMA 85B 7301-D module is 380 Watts. It requires 1.35 Amps from the 24 Volts power supply module. At 4 kilohertz switching frequency, the maximum current is 86 Amps and the rated current is 22 Amps for maximum overload conditions. Derating between 45 and 55 degrees Celsius is 1.25 Amps for 1 degree rise in temperature. Operating temperature for the DMA 85B 7301-D is 41 to 113 degrees Fahrenheit. The non-operating or storage temperature for the module is -13 to 158 degrees Fahrenheit. Housing of the module is IP 20 rated. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
