Solar Pump Inverter
Solar Pump Inverter Solar pumping system is a series-parallel absorb sunlight radiation energy through solar panels and convert it into AC power by inverter to drive centrifugal pump, axial flow pump, mixed-flow pump of deep well water pump system. According to the change of intensity of sunlight, solar pump inverter system adjusts output frequency in real time, output power close to the sun cell array maximum power.
Frequency inverter drives
Frequency inverter drives In accordance with such requirements in inverter drive markets, Gozuk launched a series of independent developed frequency inverters with high reliability, multi-function for electric motor drives. They are integrated lots of advanced control technologies, like main/auxiliary frequency reference, motor noise regulation, wobble frequency, simple PLC operation, process PID control, built-in ModBus communication, support master-slave communication between inverter drives and other features.
Non-Enclosure Variable Frequency Drive - 1HP
Non-Enclosure Variable Frequency Drive - 1HP GK3300 Series economic low cost 1HP Non-Enclosure variable frequency drive (VFD) with compact design, it's the best choice for integrate system solutions.
