(1) 32-digit high-speed digital signal processor.
(2) Speed current double closed-loops feedback control.
(3) Door machine system driven by VVVF variable voltage and variable frequency technology.
(4) Synchronous-belt drive mode without connecting rod brings about the extremely high reliability and reduces the trouble rate as well.
(5) It intellectually adjusts door opening / closing torque, brings about the more smooth&effective mute actions. It gets rid of the possibility of
(6) SMT (surface mounting technology) of printing plate reduces the area of printing plate and increases the reliability of the electronic circuit.
