1.2. Product presentation
PSDrive is a device for the control and protection of pumping systems based on the variation of the
pump supply frequency. It may be applied to both new and old systems, thus ensuring:
• energy and economic savings
• simplified installation and lower system costs
• extension of system life
• improved reliability
PSDrive, when connected to any pump on the market, it manages its operation in order to keep a cer-
tain physical quantity constant (pressure, differential pressure, flow rate, temperature, etc.) as the con-
ditions of use change. In this manner, the pump, or the pump system, is operated only when and as
much as it is needed, thus avoiding unnecessary energy waste and extending its life. At the same time
the device is able to:
• protect the motor from overloads and dry running
• implement soft starts and soft stops to increase system life and reduce absorption peaks
• provide an indication of the current consumption and the supply voltage
• record the operating hours and, based on these, the errors and faults reported by the system
•
• connect to other devices to realize combined operation
Appropriate output filters, available upon request, allow for reducing the dangerous overvoltages that
are generated in very long cables and, therefore, make the device optimal also when controlling sub-
merged pumps.
