{"product_id":"dma-085b-3301-d","title":"DMA 085B 3301-D","description":"\u003cp\u003eThe \u003cstrong\u003eBosch Rexroth Indramat DMA 085B 3301-D\u003c\/strong\u003e module is part of the \u003cstrong\u003eDMA Servo Drive Modules\u003c\/strong\u003e series, designed for three-phase drive and cold module engineering of inverters. This backplane module provides a \u003cstrong\u003e670V Input Voltage\u003c\/strong\u003e and outputs \u003cstrong\u003e400V Output Voltage\u003c\/strong\u003e, with a \u003cstrong\u003e1.35 A 24 VDC current input\u003c\/strong\u003e to power its control electronics. Intended for seamless integration with Servodyn-D systems, it serves as the central interface linking inverters via DC-link or control cables and supports both synchronous and asynchronous motors.\u003c\/p\u003e\n\n\u003cp\u003eDetailed technical specifications for the DMA 085B 3301-D include a regulated DC link voltage requirement of 670 VDC and an unregulated link of 715 VDC. The module’s maximum continuous current rating is 86 arms for overload (OL) and 64 arms for current limit (CL), with a nominal rated current range of 22 to 47 arms subject to a derating factor of 1.25 A\/K. Cooling is managed by two RMB\/DM type 2 fans and optional air- or water-based heat dissipation. The analog interface supports a 12-bit resolution encoder interface and resolver input, while the incremental encoder path leverages a SERCOS-interface position system at 1 MHz.\u003c\/p\u003e\n\n\u003cp\u003eAdditional features of the DMA 085B include high-resolution feedback with 20-bit single-turn and 32-bit multi-turn encoder support, sine and cosine encoder interpolation up to 800 kHz, and sine encoder EXE factor of 50 kHz. Efficient thermal management demands cooling water between 10–40 °C at a minimum 5 ml\/min flow, 5 bar pressure, and pH 7–8.5. With a maximum power loss of 380 W and a compact width of 100 mm, the 11.5 kg unit offers robust durability. Shipped globally with a one-year warranty, it delivers high reliability and precise control for demanding industrial automation applications.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unstocked","offer_id":52077222658349,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/DMA_Module_Series__01HRAN7Q2QMV638QNTNRSGBT13_7152a000-2daf-49ea-ba5c-a2d0bfb9b612.webp?v=1760124938","url":"https:\/\/servosupplier.com\/products\/dma-085b-3301-d","provider":"Servo Supplier","version":"1.0","type":"link"}
