ELECTRIC CONTROL PANEL WITH INVERTER

The HERTZ ONE control panel is an automatic control and protection
system for one electric centrifugal pump equipped with three phase or
singlephase motors.
The control panel power supply can be three phase or single phase.
The HERTZ ONE control panels include a pump control software and
allow regulation of motor speed via an electronic frequency changer
(INVERTER) that powers the pump motor. On varying the rotation
speed, the pump performance varies in terms of flow rate and head,
allowing optimal use in every condition and saving energy.

TECHNICAL DETAILS
• Energy saving: the controller modulates the pump according to
the hydraulic energy request of the plant with respect to a direct
connection in the network
• Quicker and improved regulation
• Hammering reduced thanks to gradual start-up and stop
• Improved comfort in the heating, air conditioning and pressure
boosting systems
• Reduced peak current
