Energy-Saving VSD Water Pump The frequency conversion drive water pump combines SPWM and pressure sensing technology, detects actual pressure change in the pipeline and achieves accurate speed control of the water pump. Features of Products ■ The frequency conversion drive water pump combines SPWM and pressure sensing technology, detects actual pressure change in the pipeline and achieves accurate speed control of the water pump. ■ Reduce mechanical stress with soft start and stop and will thus make pump’s service life longer. ■ It can work with current generators even with their temporary loads. Supply voltage range for single-phase controllers operation: 160 - 240V. Voltage range for the operation of three-phase drivers: 300 - 415V. ■ Constant pressure water supply system makes life quality better, and water usage comfortable and enjoyable. ■ Extra pump protection, provides comprehensive protection of the pump, it protects against: - short circuit, - dry running, - overload, - rotor lock, - voltage drop, - phase failure, - over voltage. ■ Water & electricity efficiency: Compared to the traditional water supply method, the variable speed inverter saves up to 60% of energy. ■ It is convenient and easy to check and set actual pressure values with the Led display.
