The safe smooth and quality operation

Frequency regulation and speed governor (VVVF) technology

(1)It fulfills speed governor control according to the human body requirements.
It brings about the more smooth and comfortable travel.
(2) The modular design structure reduces the repair cost for vast customers.
(3) The intellectual large-power module (IPM) brings about the more reliable
drive systems.
(4) There is seamless connection between circuit board and IPM module in
order to reinforce the anti-interference capacity of the systems.
(5) The blended speed testing coder increases the elevator running accuracy
with the more smooth and comfortable travel.
