DMA 085B 5311-D

Product Description

Bosch Rexroth is a seasoned manufacturer of motion control products and is based in Lohr am Main, Germany. The company operates across many countries around the world and has a total of 31,000 employees in different parts of the globe. Their products can be purchased from Wake Industrial with a one-year warranty. 

The DMA 085B 5311-D is used as a separate three-phase module in the Servodyn-D inverter system. The Servodyn-D inverters have been designed for servo applications in industrial motors. With their backplane modules, they support cold module engineering. The inverter systems have been designed with mechanics that enable the systems to deliver maximum power. The DMA 085B 5311-D is used for highly accurate speed and position control in various industrial motors. The SF, SR, synchronous and asynchronous motors can be used with the system. At 4 kHz, the device has a maximum current of 86 A and a rated current of 22 A. The values for continuous maximum current are 64 A and those of continuous rated current are 47 A. These values show a derating of 1.25 A/K in a 45 ᵒC to 55 ᵒC temperature range.

At 8 kHz frequency, the DMA 085B 5311-D has a maximum current 63 A of and a rated current of 12 A. At the same frequency, the continuous maximum current has a value of 44 A and the continuous rated current stands at 31 A. These values show no derating within a temperature range of 0 ᵒC to 45 ᵒC. Beyond this range, a 0.95 A/K derating is observed. The device also comes with inbuilt fans that are used for heat removal from the control cabinet. In addition, water cooling can also be utilized in the system for which water at a temperature between 10 ᵒC to 40 ᵒC and at a pressure of max. 5 bars must be introduced in the system.
