GRPS20 small machine room passenger lift adopts the compact small machine room layout to effectively reduce the overhead space and cut down the building cost to the full extent
The matured and reliable serial communication
The concise and reliable serial communication network is adopted between various control sub-systems in order to fulfill a series of the functions such as calling ,command group supervision signal,floor display etc. It greatly reduces the trouble possibilities out of circuit problem,largely enhances the reliablility of the lift travel.At the same time,it brings more convenient repair and maintenance to the lift system.
High efficient vector VVVF inverter
We can have precise real-time control of the motor rotating toque,ensure the smooth lift travel condition,sensitive reaction,the most comfortable start through adjusting the current and phase according to the actual load of the car,up/down speed.
