2.1 Features
SINUS MV
Standard MV VFD is manufactured by
Santerno
. It is equipment for use with medium voltage (synchronous
or asynchronous) AC motor speed adjusting and driving. It has the following functions and features:
●
SVPWM control technology has advantages of high control accuracy, fast response, and more than
98% VFD efficiency;
●
Modular design of power cell, convenient to maintain;
●
Wide input voltage range meets the demand of grid;
●
Power cells connecting in series topology and wave stacking method, well developed technique and
reliable devices;
●
Output voltage has AVR (automatic voltage regulating) voltage stabilizing function of to prevent
damage to motor insulation from over-voltage and reduce the motor wear and tear;
●
Torque boost function, raise output voltage & output torque during low frequency running;
●
Rotating speed (flying-start) start function, realize the motor restart during rotating, meet the
continuous production requirement;
●
Instantaneous power outage function, inverse charging to ensure normal running when the network
loss power in a very short time;
●
Auto-start on MV trip, suitable for working conditions like dual power switch and grip voltage loss;
●
Synchronous transfer switch function (optional), realize “no disturb” motor switch between grid and
VFD, reduce the impact to equipment and grid;
●
Power cell by-pass function (optional), automatically bypass the failure cell without influence the VFD
running;
●
English HMI easy for operation, (eight languages are optional).
●
Synchronous motor, synchronous/asynchronous start
●
Master-slave function to make multiple VFD control
●
Compact design and proper arrangement( possible to do special design according to customer
requirements)
Besides above advantages,
SINUS MV
Standard MV VFD has the following functions and features:
●
Motor over-load protection
●
Over-current protection
●
Input Phase loss protection
