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

If the pressure in the system drops by a preset difference in pressure values compared to the set pressure, the MT10 inverter switches on the pump . When the pump reaches the set pressure value, the inverter switches it off after a certain time interval.

The inverter also provides the pump with protection against dry running , overcurrent, frost, short circuit, overvoltage and undervoltage and too high a temperature of the pumped water. Control and adjustment is performed via the LCD display using the buttons. The inverter is installed between the pump and the diaphragm pressure vessel, ideally with a volume of 8 l. It is necessary to install a non-return valve in front of the inverter at the connection to the pump.
