Often considered only with larger motors, the energy saving feature of the AC drives is valid also in the low voltage range. Not having to run the motors at full speed all the time, one can obtain benefits in energy cost savings. In the low voltage AC Drives, the losses in the drive itself are minimal and high switching frequencies result in low losses of the motor as well.
The energy saving potential of AC drives is highest in pump and fan applications, but also compressors, conveyors, lifts and many more applications may benefit from AC driver control. In HVAC systems, there are numerous low voltage motors driving pumps and fans. Controlling the speed of these motors according to the actual demand of water or air flow brings considerable energy savings, because motors are the dominant consumer of electric power in the systems. Improve your HVAC system efficiency with Low Voltage AC Drives.
