Three phase 380~460V escalator controller for three kinds of energy-saving operating modes
Products features
| Build-in synchronous switching function | That can achieve a smooth switch between industrial frequency and variable frequency. |
| Excellent bypass variable frequency technology | When escalator is switching from variable frequency to industrial frequency, the excellent phase locking technology makes small current impact and no jitter in the escalator. Escalator switching from industrial frequency to variable frequency with ultra smooth speed tracking technology can realize the switching without impact. |
| Three kinds of energy-saving operating modes | Nobody taking the escalator, it will run at slow speed. Nobody taking the escalator, it will run at slow speed first, and then stop running. Nobody taking the escalator, ot will stop running., |
| Perfect escalator protection | There are multiple escalator protections for fault. |
| Four escalator running modes | Bypass variable frequency run. Industrial frequency Y-△ run. Fully variable frequency run. Inspection run. |

Production and installation size
FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
