Product description:

An ultra-high-speed motor controller product specially developed for air compressor motors in fuel cell systems. It has high control accuracy, small harmonic current, quick response, and perfect protection functions.

Features:

Conversion efficiency can be as high as 98%, saving hydrogen consumption;

Has a wide DC voltage range (250-800VDC);

Reliable and stable vector control algorithm without speed/position sensor;

High control accuracy, fast response speed,and perfect protection functions;

The output frequency can reach 0-3500Hz, and the highest motor speed can reach 210000rpm;

The output current harmonic is small,effectively reducing motor heating;

Output dv/dt is small, effectively reducing motor shaft current and protecting insulation of the motor.
