- Low Harmonics Regenerative Matrix Converter U1000
YASKAWA ELECTRIC CORPORATIONUpdated on：Apr 4, 2019
U1000 is the product applies matrix converter technology for the first time in the world.
It wipes out the existing system problems in harmonic measures and power regeneration, also contribute to the customers with energy-saving performance more than conventional inverter.
The U1000 was awarded the Minister's Prize of the Economy, Trade and Industry in 2015 which is the highest award in the Energy Conservation Grand Prize.
- Power Regeneration to Save Energy!
Generate electric power when rotate the motor and achieve energy saving with utilizing the energy efficiently.
- Low Harmonics!
Achieve the less harmonic since the sinusoidal input current is the almost same as commercial power supply.
Also, correspond to downsizing of the power supply capacity as well as Harmonic Suppression Guidelines easily.
- Compact All-in-One Unit!
Harmonic countermeasures that were previously required to connect a converter, such as input AC reactors, harmonic filter reactors, and capacitors, are not necessary, which helps you save wiring, space, and energy costs.
