A PCS typically uses a combination of reactors, capacitor cans, and controllers to improve the quality of the incoming power. In some facilities if the harmonic distortion is the main issue, we will customize the design in a way that our PCS specifically addresses harmonics and mitigates the unwanted waveforms.

If you are experiencing problems with equipment performance or reliability, or if you are using sensitive electronic equipment in an environment with poor power quality, a PCS may be necessary to protect and improve the performance of your equipment.

You can benefit from a degree of intermittent power supply failure ride-through. This is, in most cases, sufficient to ride through common upstream auto fault reclosures which are typically 240ms in duration and can cause sensitive equipment such as PLCs to reset and result in lost production time and wasted raw materials.

On top of all other benefits, PCS reduces premature wear and tear, and eventually failure, in your electrical equipment resulting in less downtime and repair/replacement costs. The quality of the power by which the loads are supplied directly affects their operation, efficiency, and lifespan. A cleaner power supply has proven to result in longer life expectancy for equipment and far less power related complications downstream.

The short answer is no. Power factor correction units just improve the power factor but cannot provide ride-throughs, harmonic filtration, voltage balancing, etc. Furthermore, usually older systems do not function well enough after several years. So, you can retrofit your existing old system with a newer, more efficient, and better solution.
