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.

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.

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

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.

• 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

Compact efficiency

Eco mode - Built-in bypass function

The U1000 has a built-in bypass function. Whenever an application is matching the grid frequency, the U1000 can synchronize the motor to grid frequency. This built-in bypass function eliminates switching losses. It also nearly eliminates current distortion and the motor noise level will be significantly reduced.

• No need for external bypass components (no phase detectors, contactors, peripheral devices, ...)
• Reduced AC drive losses
• Silent motor operation

System size reduction

Conventional dynamic braking solutions with braking units and braking resistors need lots of space and cooling. The U1000 matrix drive is a simple 3 wire in, 3 wire out configuration. This advantage in design reduces the footprint of your application, saving about 50 % on wiring and weight while also saving 100 % of wasted energy and eliminating the risk of fire by overheating the braking resistors.

Eliminate components

• No additional braking units
• No additional braking resistors
• No additional fusing

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

Built-in functional safety

U1000 comes with a built-in dual-channel safe torque off (STO) function that meets the requirements of SIL3 and PL-e, offering an easy way to improve machine safety without the need for complex external wiring.

• TÜV certified according to 
• EN/ISO 13849-1 (PL-e), IEC 62061 (SIL3)
• Simple wiring
• Less components
• Higher reliability
• Space saving
