About MD5204T22BS-INT AC Drive, Three Phase, 380V to 480V,22kw - Inovance Ac Drive
The Inovance MD520 22 kW AC Drive (Model:
MD5204T22BS-INT) is a high-performance variable frequency drive (VFD). While it delivers identical power ratings to the standard 22S variant, the
"B" designation confirms an integrated, factory-fitted internal braking chopper unit inside the chassis. [
