ZK Electric has upgraded its ZK600-P photovoltaic pump inverter, deeply integrating advanced PID control to achieve photovoltaic priority and intelligent hybrid constant pressure water supply. With an MPPT efficiency of 99.8%, multiple protections, and remote monitoring, it ushers in a "new era of intelligence" for photovoltaic pumps.

The types of fans include negative pressure fans, circulating fans, centrifugal fans, Roots blowers, boiler induced draft fans, and copper furnace blowers.

The wire and cable industry is currently moving towards greater technological development, including product diversification and automation. Powered wire feeding frames are very common in the industry. Based on their style, powered wire feeding frames can be divided into vertical wire feeding frames and horizontal wire feeding frames. Both are wire feeding devices, differing only in structure. In the wire feeding process, frequency converters have become indispensable equipment. Frequency converters can control the speed of the motor to achieve the wire feeding speed, thereby improving the process level and production efficiency, ensuring process quality, and maximizing profits.

A frequency converter is a control device that uses the switching action of power semiconductor devices to convert power frequency power into electrical energy of another frequency. It can realize functions such as soft starting of AC asynchronous motor, variable frequency speed regulation, improved operating accuracy, power factor change, and overcurrent/overvoltage/overload protection.

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.
