MVD3000 series
MVD3000 series Having adopted the leading technologies of vector control and energy feedback, the MVD3000 Series variable-frequency speed regulating system is a high-performance product with accurate speed adjustment and four-quadrant operation ability, which makes it highly reliable, user-friendly with its operating interface, diverse in communication means, complete in safety assurance system, as well as easy to maintain. With an SVM full-control rectifier, the MVD3000 power cell achieved low harmonic pollution, implemented bi-directional flow for high-power factors and energy, and is high-performing, highly efficient, and highly stable. By decoupling control of the motor flux and torque, the high-performance vector control technology used by the MVD3000 receives fast dynamic response for torque and features the ability to output high torque during motor startup and idle running speed. It achieves a more stable motor operation and more accurate speed control, which satisfies applications with higher speed adjustment. The MVD3000 supports vector control with and without speed sensors. Users can decide whether to install a speed sensor according to the applications on-site.Without a speed sensor, it can still provide fast dynamic response and greater output torque under low speed. Product Introduction Features & Benefits Advanced Technologies Adopts SVM full-control rectifier technology with a high power factor for grid access points, low amount of harmonics, higher ability to resist power disruptions, and wide range of applications. The MVD operates in four quadrants and implements fast load-side braking and grid-side energy feedback. Advanced vector control technology with and without sensor, excellent motor control performance. Advanced automatic recognition of motor parameters, DC braking, power loss crossing, synchronous/ asynchronous switching function for industrial frequency variation. Fulfills coordinated control of multiple MVDs and satisfies diverse application requirements. Features multilevel technology for cascaded cells. There is no need for an output filter. The output voltage waveform is similar to that of sinusoid waves and fulfills remote motor driving under adverse conditions. Enhanced Process & Quality Control Capability to produce large output torque at low speeds and during motor startup, increasing dynamic response speed and acquiring
