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.

​In modern industrial automation, Variable Frequency Drives (VFDs) play a crucial role in controlling the speed and torque of AC motors, greatly improving energy efficiency and process flexibility.

Constant pressure water supply system features 1. Pump soft start, stop, no impact and overpressure hazard, no water hammer phenomenon; 2. Reliable operation: the frequency converter realizes the soft start of the pump, prevents the pipe network from impacting, avoids the pipe network pressure exceeding the limit, and the pipe is broken; 3. The equipment has high degree of automation, the water supply is stable and reliable, and the water quality has no secondary pollution; 4. Perfect protection function: a single pump fails, actively sends out alarm information, and starts the standby pump to maintain the water supply balance;

Solar pump inverters have become increasingly popular in agricultural, industrial, and domestic water supply systems due to their ability to efficiently convert solar energy into power for driving water pumps.
