Delta APF2000 active power filter

Modern industry depends on automated processes and modern technologies which present nonlinear loads to the power system and contribute to a host of systemic power distortion issues, such as damaging voltage fluctuations, reactive power events and harmonic distortion. These issues can result in increased costs, protracted equipment downtime and dramatic energy losses that negate many of the efficiency gains of automation. Power quality assurance has become vital to safeguarding equipment and systems essential to today’s industrial and commercial processes.

Delta’s APF2000 Series active power filter monitors load current and filters harmonics to maintain a clean line current. Using a 32-bit digital microprocessor, the APF2000 can instantly compensate for all types of harmonics in real time with a response of less than 20 ms. The APF2000 comes in various models with current ratings of 50, 100, 200 and 300 A, and can reduce THD to less than 5% and improve power factor to over 0.96. Operating temperature range is -25 to +70°C at up to 90% RH.
