VFDs reduce energy use

A typical fan or pump running at 50% speed will use one-fifth as much energy compared to systems using mechanical control methods. For square load applications, operators can typically achieve 20 - 70% energy savings when applying VFDs to fan and pump systems while creating a more comfortable environment.

Clean grids

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.

• No oversizing of transformers, generators or cables
• Sinusoidal input current and power factor at ~ 0.98
• Compact installation - 3 wire in, 3 wire in
• Reduced lifecycle cost
• Reliable operation
• 10 years of maintenance-free design

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.

System efficiency

The AC to AC design of the matrix drive creates a sinusoidal input current. It means the U1000 provides a power factor close to 1. This near unity power factor makes it possible to reduce losses in generators, transformers, and cables. When installing the U1000 you can even design a smaller grid capacity for new installations or add more drives to existing power lines without additional stress to the power transformers.

Modernization

The Yaskawa matrix technology has been successfully proven in the field of low harmonic, space saving and regenerative applications. The direct AC to AC design advantage makes the setup more efficient and helps to save your operation cost sharing the regenerative energy with other electrical devices in the system.

• Low harmonic (keep IEEE 519 limits)
• No need for braking units and braking resistors or
• additional fusing
• Significant reduction in panel cooling requirements
• Easy conversion from an existing to a new system
• 100 % wasted energy saved
• Designed for 10 years of maintenance-free use
