Ecosine Active reduces system disturbance

Schaffner has introduced a digital system for the efficient reduction of system perturbations - the Ecosine Active.

It provides intelligent and adaptive compensation of harmonic currents with a response time of less than 300us.

It continuously measures and analyses disturbances in the power network, and provides an exactly opposite compensation current.

In doing so, the filter actively adapts to changing network topologies and responds in less than half a millisecond.

Ecosine Active enables the user to comply with stringent international harmonics standards, as well as with local utility codes.

It also ensures that the electrical infrastructure is unburdened, preventing potential overheating of transformers, motors and cables, and that the risk of premature failure of electrical equipment is reduced.

The improved power quality minimises the risk of downtime and process interruptions, while saving energy and reducing operating costs.

In addition to the global or selective mitigation of harmonic currents up to the 50th order, Ecosine Active is able to perform power factor correction in a targeted manner.

In highly dynamic processes, such as welding robots, Ecosine Active provides the required reactive power within microseconds, significantly faster than traditional automatic capacitor banks.

Ecosine Active is easy to install and intuitive to operate, and its compact package makes its use possible even when space is at a premium.

The 50 and 100A filters in the IP20 design are ideal for panel integration, so they can be installed right by the non-linear load.

The IP54 rating of the 300A unit provides protection against dust and environmental influences, making it ideal for harsh industrial applications.

Ecosine Active is available in three-phase/three-wire, as well as three-phase/four-wire configuration for 480V and 400V grids, respectively, and with rated compensation currents of 30 to 300A.

All three-wire filters are UL-listed, and therefore ready for the North American market.

Building technology and HVAC installations, heavy industry, data and banking centres, UPSs, water/wastewater treatment facilities, or welding equipment can all benefit from the use of Ecosine Active.
