CPS 10 NOCCHI electronic frequency converter

Advantages of the CPS 10 NOCCHI Electronic Variable Frequency Drive

CPS is an electronic device able to vary the frequency of an electric pump. Directly integrated into the motor, it allows the speed to be adjusted so as to always supply the same pressure to the installation even when the water demand changes.
CPS is a compact, essential, reliable and easy to use solution; also designed to provide high comfort and application benefits in irrigation, greenhouses, light industry, fountains and water features.
The system is made up of an electric pump and an electronic control system (variator) that allows maintaining constant pressure on the system, reducing or increasing the rotation speed of the electric pump motor .
When the pressure in the installation drops below the selected threshold, the module starts the pump to restore the set point pressure.
The rotation speed of the pump varies according to the water demand . If there is more demand, the speed will increase to the selected maximum speed.
When the water demand drops, the pump speed will decrease to the minimum speed, after which there will be further pressure drops (i.e. new water demands) the pump will will stop (Stand By) until a new cycle begins.
