A Variable Speed Drive (VSD) also known as an Adjustable Frequency Drive, Variable Frequency Drive, or an Inverter, adjusts a motor’s speed to closely match output requirements, rather than just running at full speed all the time.
Variable Speed Drives when fitted to AC Induction motors will reduce the electricity they use and cut your energy costs.
Using a VSD to slow a fan or pump motor from 100% to 80% can save as much as 50% of the energy used. Every fan, pump or HVAC motor above 1.1kW needs a VSD and every motor deserves eVSD
Efficient Power Solutions market leading eVSD solutions give you control over your motors, cut your electricity bills providing a quick Return on Investment.
The Carbon Trust recommends VSDs as a key energy management and energy reduction tool.
