Optidrive Elevator variable frequency drive powers new Traction Controller


Smooth and reliable motion is crucial for the safe and comfortable ride of an elevator. Lester Controls wanted to ensure it was using the best VFD motor controller possible.


The compact size of the Optidrive Elevator, along with its reliability and and ability to provide maximum ride comfort in all conditions was a factor in choosing Invertek's specialist drive.


Lester Controls, the UK’s largest independent lift control panel manufacturer, has chosen the Optidrive Elevator variable frequency drive for inclusion in its latest product, the LesterXpress Traction Controller.

Size 3 IP20 Optidrive Elevator drives are built into in every control unit following successful tests at the company’s Surrey HQ.

“Optidrive Elevator is ideal for this application. It is small in size and has a built in RFI filter, it costs less than similar products of its type and above all it is extremely easy to set up and use,” comments John Beresford, Lester Controls Managing Director.

The Traction Controller is designed and built specifically to address the need for customers requiring high quality and reliability in basic lift controllers that are delivered to site from stock within a maximum of two weeks.
