The Altivar 680 and Altivar Regenerative 980 Compact Low Harmonic Drives are a packaged, high-performance solution for low-harmonic applications. These active front end (AFE) drives feature a three-level input switching stage, which reduces common mode voltage and improves performance and efficiency. These benefits are a result of the new Drives’ custom filtering and three-level design.
This new technology reaches a total distortion factor of around 2.3% and therefore fulfills the requirements per IEEE 519. This low-harmonic drive includes an efficiently designed input filter which reduces common mode voltage prolonging motor lifetime. This filter also allows the drive system to provide near sinusoidal input current regardless of percent input phase unbalance. These robust, adjustable speed drive systems are UL 508A Listed, are available in Type 1 and Type 12 enclosures, and are compatible with generator sourced power.

- In high-demand applications where harmonic mitigation and the ability to handle regenerative loads is necessary, the Altivar 980 is the solution. In upstream production, such as rod pumping, the ATV980 can provide flexibility in regenerative applications by avoiding the use of braking resistors. In addition to its compact nature, internal application functions such as ENA (Energy Adaptive Function) allow for greater energy savings.
