With  the  adoption  of  advanced  and  reliable  PI  high-frequency full-range broad-width power supply control solution, it conforms to the  standard  input  power  of     AC100-250V/50/60Hz.Its  voltage, current,  revolving  speed  and  relative  centrifugal  force  of  sectional speed can be controlled more accurately guaranteeing longer motor lifetime as well as a constant speed which will not change as voltage or load varies.

Faster acceleration/deceleration rate enables it to finish the experiment as required in a shorter time, and it will reach over 95% of the rated speed within three seconds after acceleration; Deceleration is more  user-friendly,  which  two  options,  pressing  the  door  opening key  will  activate  free  stop  in  no  more  than  15  seconds,  while  a completely  opened  cover  will  activate  braking  and  deceleration  in no more than three seconds.
