True
Active Filter The Mesta DPM is a true active filter, continuously monitoring the load
currents and responding to the amount and type of harmonics
encoun
tered. The system injects a corrective current, dramatically reducing the line current harmonics and compensating for any fundamental phase shift. The result is a "harmonicless", in-phase line current with near UNITY power factor.
Effectively reduces Harmonics The Mesta DPM reduces harmonic distortion to less than 5%,while balancing the power and improving the power factor to the plant utility grid.
Helps meet ANSI/IEEE-519-1992 Requirements When placed on a plant load, it helps meet the ANSI/IEEE-519-1992 Requirements, under all constant or variable load conditions. Mesta DPM reduces Harmonic distortion to less than 5%, while balancing the power and improving the power factor to the plant utility grid.
Highly Sophisticated Microcontroller Intelligence The patented design of the MESTA DPM incorporates a powerful microcontroller, DSP microcomputer, and the use of highly sophisticated software.
Sizing a DPM When sizing a DPM to your facility, you need only consider the harmonics and fundamental phase shift. The DPM Current rating indicates the amount of correction current that the unit is capable of producing. As an example, a 125 HP motor drive with 32% THD would have approximately 40 amps of harmonic current. If there is also 25 amps of reactive current, the filter will generate a total of 48 amps of correction current. Therefore, installing a 50 amp DPM corrects the harmonics and reactive current, even though the drive draws 130 amps of total current.
