Motor power optimisers

When running at low load, electric motors are less efficient. A motor power optimiser (also known as load sensing optimisers) could save between 5 % and 15 % on electricity. Motor optimisers are solid-state devices that automatically monitor the load on an electric motor. Under low load conditions...
