PST2280 Power Factor Controller

Beskrivning

General

With the PST2280 Power Factor Controller the currents caused by reactive power losses can be minimized, and thereby optimizing the transfer of energy between generation and load. This is getting more and more important when saving energy is vital in a world with focus on pollution and shortage of energy.
