U1000

Low harmonics regenerative matrix converter

A class of its own

The U1000 is a highly efficient AC drive based on latest matrix converter technology. With full power regeneration capability, the U1000 offers great energy saving potential while sinusoidal input currents and a power factor close to one reduce stress on grid components like transformers and power lines. With an ultra-compact shape, the U1000 is the first choice for innovative, energy-efficient drive solutions with or without power regeneration.

Innovative matrix technology

Active Front End design without conventional DC bus capacitor inside.

Clean
power

Harmonic pollution (THD-i)  below 5%.

Energy saving
4Q operation

100% braking power savings.

Revolutionary design for low harmonics

The U1000 has a unique and innovative design which exceeds the performance of general-purpose AC drives. This pushes the best-in-class AC drive not only to improve the application performance but it also exceeds the IEEE 519 harmonic guideline for the power quality which helps you to keep the power supply clean from any pollution.

Ultimate performance

 

 

 

 

 

U1000 is designed for rough applications. This extremely compact all in one solution offers optimum performance for standard and regenerative applications.

Regenerated power

The best-suited solution for regenerative applications. The U1000 eliminates the need to install external braking units and braking resistors. It returns the regenerative and the braking energy directly back to the power supply.

Built-in power regeneration

The U1000 is a very compact AC to AC drive, which means there is no DC bus inside. This innovative design does not need any braking resistor option which typically wastes the regenerative energy in heat. Now the regenerative energy can be used by other consumers in the same grid, saving total energy cost and consumption while also reducing the panel cooling system requirements.

  • Saves energy
  • Less heat generation, reduced need for ventilation
  • No braking resistor - greatly reduced risk of fire
  • Less maintenance
  • Less parts
  • Compact design

Compact and easy

The U1000 design advantages, compared to conventional dynamic braking solutions, continues in saving installation space (up to 50%), reduced weight and 100% save of wasted energy. All you need to connect is 3 wires in and 3 wires out.

  • Smaller panels
  • Very compact footprint
  • Simple installation in shortest time
  • Perfectly fits in existing installations - easy retrofit

Reliability and efficiency on board

 

 

 

 

 

U1000 is approved for global marine installation. Compared to 12 pulse systems the Yaskawa matrix design provides significant footprint and weight savings, keeping the THDi within the IEEE 519 limits.

Clean currents

U1000 is the answer to power quality, energy savings, and system efficiency improvement. The advanced technology of the Yaskawa matrix drive combines all application key features in a single space-saving drive design reducing THDi to 5 % without the need for external transformers or heavy filtering.
