PowerXL Enclosed Drives by EatonEnclosed variable frequency drives

PowerXL Enclosed Drives offer advanced harmonics mitigation, energy efficiency, and increased reliability to the water/wastewater, irrigation pumping, oil and gas, and industrial infrastructure industries. PowerXL Enclosed Drives offer standard configurations that are pre-engineered to provide a robust solution with reduced lead time, while also providing customers with custom-engineered configurations that are designed to meet specific application needs. Eaton’s PowerXL Enclosed Drives offering includes advanced harmonic mitigation packages that substantially reduce the harmonics in a system and are in compliance with guidelines such as IEEE 519. PowerXL Enclosed Drives provide superior reliability through a robust design that is tested and listed to UL 508C standards.


SC9000 encapsulated powerpole (EP) arc-resistant drive by EatonArc-resistant medium-voltage drive

Eaton’s SC9000 encapsulated powerpole (EP) arc-resistant drive is a fully integrated arc-resistant medium-voltage drive certified to CSA C22.2 No.22-11 and witness-tested to IEEE C37.20.7 through extensive assessment at a third-party laboratory. The drives build on Eaton’s highly reliable and award-winning SC9000 EP platform, allowing customers to achieve energy savings while reducing facility downtime and enhancing personnel safety. Eaton engineered the solution with arc-fault-detection circuits to prevent the possibility of an arc fault upon powering the drive. Should an arc event occur after power-up, Eaton’s patented inverter encapsulation and short circuit protection technologies help prevent fault propagation and limit arc fault energy.


Z1000U HVAC Matrix Drive by Yaskawa America Inc.Low-harmonic HVAC drive

Yaskawa’s Z1000U HVAC Matrix Drive provides extremely low harmonic distortion in a space-saving design, along with the same HVAC-specific features as the standard Z1000. This single-component solution achieves excellent low-distortion levels all by itself, completely without the need for additional countermeasures such as passive filters or multipulse arrangements. Yaskawa’s Matrix technology employs a system of nine bi-directional switches that are arranged in a matrix to convert a 3-phase ac-input voltage directly into a 3-phase ac-output voltage. It eliminates the need for a rectifying circuit and a dc bus used in traditional ac-drive inverters.
