Product Description
The DMA 85B 1201-D by Bosch Rexroth Indramat is a high-performance module intended for use in conjunction with synchronous/asynchronous motors. It has an air-cooling heat loss method, and its width is rated at 100 mm. For device communications and control, the DMA 85B 1201-D utilizes a SERCOS interface with a gear encoder. Also, it is a standard variant in the DMA series from Rexroth. This module is easy to install and commission, and it offers a quick response time.
The SERCOS interface utilized by the DMA 85B 1201-D is a powerful 32-bit signal processor that confers an excellent digital control of current, speed and position. This inverter module is intended for use only in industrial areas because of its tendency to cause radio interference. Prior to putting this module to use, the corresponding machine must the required standards and specifications to avoid damage to the equipment. The DMA 85B 1201-D belongs to the protection class IP 20.
With respect to the ambient temperature and heatsink on the DMA 85B 1201-D, it automatically limits the peak current based on the power semiconductor’s thermal limit. The 24 V power supply module of this unit has a current rating of 1.35 Amperes. The Direct Current link voltage of the DMA 85B 1201-D is 670 V when regulated and 715 V under non-regulated conditions. The peak power dissipation in a switch cabinet is 380 Watts. It has a maximum current rating of 86 A and a rated current of 22 A at a switching frequency of 4 kHz. At reduced equipment specification and a temperature range of 45 to 55 degrees Celsius, the current rating of this unit is 0.95 Amperes/K. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
