Variable Speed Drive SF850
The basic function of a VSD is to control the flow of energy from the mains to the process. VSD sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor.
Product Characteristics
SF850 series drive adopts the European-type modular design scheme. Unique structural design. Make everything easy in the process of use!
1．Easy to install
◇ Key hole design
◇ Guide rail installation
◇ Spring-snap control terminal, no screwdriver required.
2．Convenient application
◇ Change the control module arbitrarily
◇ Can expand multifunctional I/O module, PG card and bus module at will
◇ Add software application macros for easy debugging
◇ Parameter copy function.
3．Simple after-sales repair
1) It can be replaced damaged unit, such as OP panel, CM control module, PM power module, PG expansion module, fan;
2) When the PM is damaged, there is no need to replace the CM, which is convenient to replace without adjusting the parameters and control lines, greatly saving the after-sales cost and labor cost.
