+Advantages of CNweiken AC drives
We have sophisticated engineers, scientific producing workmanship and management team with rigorous quality control systems , frequency inverter are equipped with advanced features as below:
01 Remote monitoring through RS-485;
02 Built-in MPPT solar controller;
03 Compatible to utility or generator input;
04 Supports three-phase asynchronous motor;
05 Soft start function prevents water hammer effect and extends system lifecycle;
06 Compact size, easy to install;
07 485 communications, external high precision PID, multi-speed and simple PLC, swing frequency , fixed length and counting function.;
08 Soft starter inspects motor feedback voltage to realize closed loop control, ensure the motor start-up success in different conditions and different loads;
09 Reduce the starting current, reduce power supply peak current, reduce the cost of distribution equipment. Reduce the abrasion of motor, improve the service life of mechanical equipment;
10 Perfect and reliable protection function: loss of voltage, less voltage, over voltage protection; overheating, starting time too long; Input phase lost, output phase lost, three-phase imbalance; starting over current, overload and load short circuit protection, etc;
