Product Description:

The Kollmorgen MMC-SD-30.0-460-D(M.3000.0021) is a component of the MMC Standalone Smart Drive Series that is developed for advanced industrial applications that require precise motion control. The specific model M.3000.0021 design of this standalone smart drive is indicative of Kollmorgen's reputation for innovative and durable solutions. The MMC-SD-30.0-460-D MMC Standalone Smart Drive can deliver a continuous current of 69.3A and a maximum current of 110.0A, which allows for the reliable management of variable loads. A 480V, three-phase AC supply is used to power the drive, and a 56A AC line filter supports it. This filter ensures that the power input is clean, which in turn ensures that the drive will work consistently. An efficient solution for the dissipation of energy is provided by the external shunt resistor kit, that has a rating of 18Ω and a constant power output of 3900W.

The maximum amount of power that it can handle is 70 kW, and its time constant is 70 seconds when operating at 850V. The system's capacity to manage excess energy during dynamic deceleration is improved by this design feature, which guarantees long-term operational reliability. The smart drive is suitable for various industrial automation applications due to the MMC-smart drive configuration, which facilitates integration with complex motion systems. The MMC-SD-30.0-460-D MMC Standalone Smart Drive essential specifications also include strong protection features that improve thermal management and longevity, as well as compatibility with high-efficiency cooling systems. The drive can handle complex automation duties with optimal efficiency and provides high-performance operation, with a power rating of 30.0 kW. We guarantee the highest quality standards by offering worldwide shipping and providing a one-year replacement warranty.
