Falowniki PWM

The Active Driver devices are innovative variable speed electric pump integrated control systems, capable of maintaining a constant pressure in relation to the varied low rates. The set pressure can be adjusted and the various settings and related error warnings can be viewed, thanks to a simple and immediate user interface.

Active Driver is made up of:

• - an inverter
• - a pressure sensor
• - a flow sensor

Some advantages in using Active Driver:

• - greater comfort
• - greater energy saving
• - greater noise reduction
• - reduced dimensions
• - eliminates overpressures
• - increased lifespan of the electric pump
• - easy installation
• - capable of controlling many different types of electric pumps

Active Driver is equipped with a malfunctions protection system.

In the event that a malfunction is verified, it is signalled on the display and, depending on the type of error, the electric pump can turn off.

• - protection against dry-running
• - amperometric protection
• - electric pump overheating protection
• - protection against abnormal power supply voltages
