Power Factor Controllers Q & A
Q: What's the typical payback period for PFCs?
A: Most installations recoup costs in 12-18 months through energy savings.
Q: Can PFCs work with generators?
A: Yes, but require special models with slower switching times.
Q: How often should capacitors be replaced?
A: Quality capacitors last 7-10 years under normal conditions.
Q: Do PFCs require regular maintenance?
A: Basic visual inspections quarterly; comprehensive checks annually.
Q: What's the difference between 6-step and 12-step controllers?
A: 12-step offers finer correction but costs 20-30% more.
