PID feedback closed loop control & V/Hz control frequency converters (AC VFD drive)

PID feedback closed loop control and optimized scalar control (V/Hz control) variable speed drive (frequency converter)
 
SHENZHEN, China - Sept. 12, 2013 - PRLog -- first rate general purpose Volts per Hertz (V/F) control VVVF drives, with built-in PID controller:

Better scalar control (V/Hz control) univeral AC inverters, with built-in PID controller for closed loop control, there are 2 analog inputs, 2 analog outputs, 4 digital inputs, and 1 digital output.

Vector Control 1 (optimized scalar control, PID closed loop control, multi-step speed setting):

Offering excellent vector control performance and insensitive to motor parameters.

Startup torque: 0.50Hz 180% rated torque

Speed adjustment range: 1:100

Speed stabilization precision: +- 0.5%

0.50Hz controllable motor stable operation with 150% rated torque (large torque at low frequency).

failure rate: < 1%, similar as Siemens, Emerson Control Techniques, ABB, Danfoss, Eaton, Schneider, Allen Bradley, Lenze, Yaskawa

authorized CE, issued by ECMG

18-month warranty period

prompt delivery lead time: 1-3 days

supply to REGAL, Ingersoll Rand, Foxconn, CG Group...
