Why Low Harmonics and Active Front End are important

LHX Series drives by Phase Technologies


In today’s world, maximizing energy efficiency while maintaining regulatory compliance is becoming less of an option—it's becoming essential. That’s why we’re excited to carry Phase Technologies, LHX Series Variable Frequency Drives (VFD) with an Active Front End (AFE), and fully compliant with IEEE 519 harmonic standards. Planning for the future has never been easier. 


 

Why Choose Our VFD with AFE? 

  1. Unparalleled Power Quality LHX Series VFDs with Active Front End drastically reduces harmonic distortion, ensuring total harmonic distortion (THD) at the point of common coupling is well within the limits specified by IEEE 519. This means cleaner power, reduced stress on your equipment, and less interference with neighboring systems. 
  2. Enhanced Energy Efficiency By using regenerative braking capabilities, this VFD allows energy generated during deceleration to be fed back into the grid. This minimizes energy waste and reduces operating costs—perfect for applications like cranes, conveyors, and elevators. 
  3. Improved System Reliability The Active Front End eliminates the need for bulky harmonic filters and external transformers, simplifying your setup while improving reliability and uptime. The result? Less maintenance, fewer failures, and significant cost savings. 
  4. Regulatory Compliance Made Easy Stay ahead of the curve with guaranteed compliance to IEEE 519. Whether you're expanding operations or maintaining existing systems, this VFD ensures you're meeting grid codes and protecting your infrastructure investments. 
  5. Flexible and Scalable These unique VFDs are customizable to meet the demands of all industries such as manufacturing, HVAC, oil & gas, and water production and treatment. 
  6. Cost Savings Across the Board Between energy efficiency, power factor correction, and lower harmonic mitigation costs, this VFD is an investment that pays for itself. 

Don’t Settle for Ordinary 6, 12, or 18 pulse drives and addition harmonic filters. 

With our LHX Series VFD offering, featuring an Active Front End and IEEE 519 compliance, you're not just investing in a drive—you're investing in the future of your operations. It's time to cut energy waste, meet compliance standards effortlessly, and keep your systems running at peak performance.
