Active Harmonic Filter – Wall and Floor Mounted
MAKPOWER Technology's active harmonic filters are available in two different forms: wall-mount and floor-mount. Wall-mount configuration is recommended for filters with 70A or less current rating. For current ratings above 70A, floor-mount panel is the recommended solution. Wall-mount products are comprised of up to two power module and a single display/communication module. Floor-mount configuration is highly modular with holding up to seven hotswap-supported power modules within one cabinet and suppoting unlimited number of parallel units.
MAKPOWER's Active Harmonic Filters help to remove harmonic distortion from the power network and avoid problems arising due to low power quality. Variable frequency drives, UPS systems, computers and energy saving light systems cause harmonic distortion levels beyond acceptable limits. High harmonic distortion reduces equipment lifetime and causes productivity loss. Unbalanced loads such as computers cause excessive neutral currents and 3rd harmonic currents to flow on the neutral wire. This results in unacceptable voltage levels between neutral and earth, and may lead to equipment malfunction and physical danger.
MAKPOWER's Active harmonic filters provide a complete solution for facilities with dynamic variations in the load harmonic distortion, load imbalances and single phase loads with high level of current harmonics on the neutral wire. Active harmonic filters are connected in parallel with the load or facility. They measure and analyze the harmonic content of the load or line currents and inject a compensating current into the grid to cancel the harmonics. As a result, the harmonics on the line currents are eliminated and the neutral wire is off-loaded. Active harmonic filters guarantee less than 5% current total harmonic distortion (THD-i) even in facilities with highly dynamic and harmonic loads. Active harmonic filters also help dynamic power factor correction with %100 inductive and capacitive support. System reacts to load changes withing 25ps.
