The ZK Four-Quadrant Vector Inverter adopts PWM-controlled IGBT rectification technology to achieve bidirectional control of rectification and energy feedback. With a power factor close to 1, it enables true four-quadrant operation. This series of inverters can feed back the inertial energy of the load to the power grid, and is equipped with regenerative function and braking function. It is suitable for potential energy loads requiring energy regeneration, energy conservation and environmental protection, as well as large-inertia loads requiring rapid deceleration. As a high-performance energy-saving product meticulously designed by Kewol Electric to meet customer needs, it delivers significant energy-saving effects.
