GK620E Elevator dedicated AC Drive

GK620E is dedicated for passenger and freight elevators installed in residential buildings, shopping malls, and office buildings. The drives can be programmed to have a commendable leveling even they adopt open-loop control, reducing the cost of additional devices. Flexible S-curve program greatly improves comfortabilty for the elevator users.
