Product Description
Product Overview
Qi’an 18.5kW high-performance controller featuring low noise and low vibration. It’s a permanent-magnet synchronous motor controller, with all components 100% domestically produced. The input voltage is 600VDC, and the input stage incorporates multiple filtering measures to minimize electromagnetic interference before being converted into AC power via an IGBT inverter to drive the motor. The equipment boasts excellent electromagnetic compatibility.
Rated power: 18.5kW
Input voltage range: 600VDC
Rated output current: 60A
