KE300A-09 Series Digital Potentiometer Special Inverter

DigitalPotenTIometer (CNC programmable resistor) is a new type of integrated circuit for CMOS digital and analog mixed signal processing that replaces traditional mechanical potentiometers (analog potentiometers). The digital potentiometer is controlled by a digital input and produces an analog output. Depending on the digital potentiometer, the maximum tap current can be from a few hundred microamperes to a few milliamperes. The digital potentiometer adopts numerical control to adjust the resistance value. It has the obvious advantages of flexible use, high adjustment accuracy, no contact, low noise, not easy to be damaged, anti-vibration, anti-interference, small size, long life, etc. It can be replaced in many fields Mechanical potentiometer.

Features of KE300A-09 Series Digital Potentiometer Special Inverter

(1) DSP high-speed control core

The control core adopts the high-speed digital processor DSP produced by TI (Texas Instruments). Ensure the system has strong performance with high speed and stability features. It can completely deal with the most complex control operations.

(2) New No PG vector control technology

No PG vector control can block the motion, the rated torque can up to 150% when it is 0.5Hz ; It can help to reduce the sensitivity to motor parameters and improve the adaptability at the site. It also can be applied to winding control, That's a perfect solution for multiple motors drag the same load.

(3) Characteristics of "excavator"

(4) Fast dynamic response

The dynamic response time under PG vector control is less than 20ms.

(5) Fast current limiting function

(6) Accurate parameter identification ability

(7) High torque control accuracy
