SUPER ENERGY SAVING MEDIUM VOLTAGE INVERTER Puts the Brakes on Global Warming!

Muffles High-Frequency Noise and Eco-Friendly Super Energy Savings. In 1996, Yaskawa introduced Japan's first commercially produced PWM (pulse-width modulation), medium-voltage inverters with multi-outputs connected in series. Building on this pioneering technique, Yaskawa has made even further improvements. The FSDrive-MV1S inverter is the result of Yaskawa's search for an inverter that is both easy to use and offers improved operability and monitoring. By using the FSDrive-MV1S with either general purpose machines or those powered by wind or water, you can dramatically reduce CO2...

The Latest Technology Brings Even More Stable Operation. HiShrJeyeJ Control Full-scale flux vector control improves starting torque characteristics and responsiveness to fluctuations in the load, without using a speed detector. Attain stable operation even when there are load fluctuations. Medium-voltage Three-phase Induction Motor Speed Search Function The inverter continues to operate during a momentary power loss of several cycles*1. The inverter re-accelerates to the reference speed almost at the same time as the power is restored to ensure that the drive starts ♦ 1 : Holding time...

QP.®ration_UsJnjg[.Multiple Motors Parallel operation of mutiple motors with one inverter is possible and the scale reduction of the drive equipment is possible. Inverter Panel Motor Note : In multiple motor operation models, each motor requires a protective device. High efficiency drive is realized by minimizing the motor current to the required output torque. In this way,outstanding energy saving effect is shown in the drive of fans and pumps to machines for general use. Easy Maintenance Easy to manage power cell structure, and improved monitoring for reduced down time. Individual Cell...

Standard Specifications The PWM Control with Multi-output Connected in a Series Helps Protect Nature, Power, and the Machine. The Most Efficient Use of Energy Since this Inverter is a direct medium-voltage inverter that does not need an output transformer, it can maintain a power conversion efficiency of approx. 97% so as not to waste energy. Power supply factor is always kept at approx. 0.95. Since the power factor does not change even if the operation speed changes, no power factor improvement capacitor is needed. Perfect Harmonics Measure The input waveform is sinusoidal wave and rarely...
