An Elevator controller is a system to control the elevators, either manual or automatic
The controller usually tune down the voltage between 12v to 24v to the controlling system,
Only the motor needs 3-phase power supply. The low voltage power is for the controlling
component and the fixtures to control the elevator
Microprocessor based controllers are very compact and consume a lot less power in
comparison to the older electro-mechanical relay controllers.
