Inovance MD290T55G/75PB-INT: 55 kW heavy duty (G) / 75 kW normal duty (P), three-phase 380–480 V, 112 A / 150 A, frame T7. It is a genuine Inovance MD290 series drive from Shenzhen Inovance Technology.
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.
