HD31 Multi-pump Water Supply Special Inverter
HD31 is a product specially developed for multi-pump water supply industry based on HD30 vector control inverter. Three-phase 380-460V, 5.5-132kW can be used in municipal water supply, sewage treatment, agricultural irrigation, etc.
Timed segmented constant pressure water supply
A maximum of 12 timing sections can be set to adjust the pressure of the pipe network to achieve a timing and constant pressure control of water supply.
Power frequency/variable frequency pump timing rotation control
It can realize the timing rotation of power frequency pump or variable frequency pump.
One drag for more water supply
Up to 7 water pumps can be controlled.
Two energy-saving sleep modes
More energy-saving options.
Perfect detection function
Water level detection, pipe network pressure detection.
Automatic elimination of faulty pumps
It can automatically eliminate the faulty variable frequency pump in the system and start the next pump at the same time.
Pump starting principle: first variable frequency, then power frequency.
Smooth pump switching function
Ensure the pressure of pipe network is stable.
