The Inovance MD520‑4T22B is a powerful 22‑kW three‑phase AC drive within the reliable Inovance MD520 series, designed for precise speed and torque control for industrial asynchronous and permanent‑magnet synchronous motors. Running on 380‑480V three‑phase power supply, the Inovance MD520‑4T22B comes with built‑in braking unit to handle frequent deceleration for heavy‑duty industrial equipment.
Featuring advanced SVC open‑loop and FVC closed‑loop vector control algorithms, the Inovance MD520‑4T22B delivers 200% high starting torque at zero speed. It supports 150% overload for 60 seconds, making the Inovance MD520‑4T22B well‑suited for heavy‑load cycles with repeated start‑stop operations. Smooth motor performance avoids speed fluctuation even under variable load conditions.
Reliability stands out for the Inovance MD520‑4T22B. Conformal‑coated circuit boards boost resistance against dust, moisture and high‑temperature workshop environments, lowering unexpected downtime and extending service life. This Inovance MD520 series inverter meets strict EMC standards and works stably alongside other site automation hardware.
For system integration, the Inovance MD520‑4T22B supports multiple industrial communication protocols, compatible with mainstream PLC and control systems. Adjustable carrier frequency from 0.8kHz‑16kHz cuts motor noise. Built‑in functions include fault diagnosis, brake management and flexible logic settings, reducing extra hardware investment for machine builders.
Widely deployed for conveyors, mixers, crushers, fans and pumps, the Inovance MD520‑4T22B is a cost‑effective vector inverter choice for automation integrators and equipment manufacturers worldwide. It balances solid performance, stable quality and competitive pricing as a practical alternative to imported AC drive.
