What is PQS?
PQS is a 0 to 200 rating of efficiency, Power Factor and Total Harmonic Distortion – like MPG for power electronics. A high PQS means that the product is using all of its energy effectively. A low PQS means the product is wasting energy.
By using PQS to select effective and efficient electronic devices throughout a residence or commercial facility, we estimate a 10% reduction in energy demand, thereby reducing carbon footprint while saving money.
