Water-cooled frequency converter with an integrated pressure and flow monitor for regulating pump speed. The converter controls and maintains a constant, pre-set pressure level. Designed for use with clean, non-aggressive water. Up to two pumps can be connected in series to the converter.

If the pressure in the system drops below the set pressure by a pre-set pressure difference, the MT10 converter will activate the pump. Once the pump reaches the set pressure value again, the converter will turn it off after a certain time interval.

The converter also provides the pump with protection against dry running, overcurrent, freezing, short circuits, overvoltage and undervoltage, and excessively high temperature of the pumped water. Control and settings are managed via an LCD display using buttons. The converter is installed between the pump and a pressure membrane tank ideally with a volume of 8 litres. It is essential to install a check valve on the connection with the pump before the converter.
