Financial and other benefits of DC to AC conversion

This article form Sentridge Control explains the benefits of switching from DC to AC drives - including the potential for making energy savings worth thousands of pounds per year.

Companies using DC systems have saved thousands of pounds per year in energy costs, as well as reducing maintenance costs and increasing flexibility, through DC to AC conversions. If a free Sentridge Control DC to AC conversion trial and energy audit indicates that savings could be made, the company can proceed with replacing the active motors and installing appropriate variable-speed drives. Note that data is collected over a seven-day period to give an accurate picture of the energy consumed and the potential for savings.

Reducing energy consumption will lead to direct savings in energy costs, plus it can help companies with their Carbon Reduction Commitment. Typical energy savings are in the range 20-3- per cent, which has a significant impact on the carbon footprint too.

As well as reducing energy costs, a DC to AC conversion can also eliminate or reduce the following problems and costs:

  • Brush inspections and replacements
  • Filter replacements
  • Oil checks/changes
  • Commutator checks
  • Bearing checks
  • Wear checks
  • Lubrication
  • Spare parts/motors

Sentridge Control provides a full specification, installation and commissioning service, ensuring that downtime is kept to a minimum - installation and commissioning is often completed within one day.

A proud founder member of the ABB Drives Alliance, Sentridge Control has over 20 years' experience in installing and commissioning AC variable-speed technologies, offering customers a comprehensive service rather than simply supplying drives.
