Application

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.
