The Only Manufacturer of Both Elevator Controller and PM Traction Machine in China!

Bluelight Car Door Integrated Controller


Car Door Integrated Controller




· Features

Adopts advanced vector control technology to increase running accuracy and stability.

Complete protecting and intelligent processing system to guarantee driving safely and reduce maintaining cost.

Features non-encoder asynchronous door motor drive function to system cost and risk of failure.

Multiple terminal types for I/O ports to support feasible connection methods.

High compatibility with peripherals and support easy connection when working solo as door motor controller.

When working in Bluelight control system, the controller combines full functions of Car Top Control Board and Car Door Motor drive, so no Car Board or Car Top Control Board is required.

 Featured with LED button control and Bluelight Digital Operator control for easy operation on site.
