Reliable power distribution is needed to guarantee patient health and save lives in hospital. Continuity and reliability of power supply are extremely important in hospital.UPS,Generator,Medical devices include high volume of harmonics current, and can impact the distribution system in hospital.
ZDDQ Active Harmonics Filter
Based on the broad knowledge and experience in terms of solutions and applications in power quality the ZDDQ has developed a new generation of active harmonic filters. Our new modular Active filters offers fitted and economical solutions for the most demanding harmonic mitigation challenges with any kind of non-linear load involved. ZDDQ active filter series provides a solution concept which is modular, compact and can be used as stand-alone modules or as system solution.
The optional AHF module offers a smart load Management of the filter’s usage and allows redundancy which guarantees a smart power quality solution in the era of Industry 4.0.
ZDDQ provides active harmonic filters with excellent performance in solving power quality problems focusing on customer needs and application demands for cleaner and smarter energy.
