High-mid voltage solid soft starter.
RNMV has following special functions:
1 The main control panel has passed the strict EMC electromagnetic compatibility test has better electromagnetic interference-resistant performance.
2 Possess exclusive intellectual property in control technology of soft starter,and are able to provide updating service of the soft starter control system for free.
3 Negtive feedback function. by which, the artificially setted starting curve cannot
match the load moment curve are solved.
4 Better adoptive capacity.
5 Free stop or soft stop is optional.it may suit various stop circumstances such
as eliminating water hammer effect of the water pump to meet special requiremnets.
6 System communication funciton.Internal communication port to realize.
point-to-point communication between RS-232 and computer.RS485 may realize multi-point communication with remote terminal units(communication protocol Modbus or Porfibus is optional).Remote control and remote signaling function could be realized by linking to upper PC communication.
