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.
