Genuine Inovance MD290 drive MD290T45G/55PB-INT – 45 kW heavy duty (G) / 55 kW normal duty (P), three-phase 380–480 V, 91 A / 112 A, frame T7.
The MD290 is Inovance’s general-purpose open-loop AC drive for variable-torque and constant-torque loads; it carries a G (heavy duty) and a P (normal duty) rating in one unit, so the same drive covers a larger pump or fan motor at 110% overload.

Compatibility and replacement
Order with the complete model MD290T45G/55PB-INT: in MD290 codes the T stands for the 400 V class, 45G/55P gives the heavy-duty and normal-duty ratings, B the built-in braking unit and -INT the international version.
The ratings in the table are taken from the official Inovance MD290 brochure (inovance.eu). If your old drive shows different values, send us a photo of its nameplate and we will check it.
Before you replace it
- Motor rated current and the duty (heavy or normal)
- Frame size and mounting holes in the cabinet
- Supply voltage and number of phases
