MCE/P INVERTER
CONSTRUCTION FEATURES OF THE ELECTRONICS: MCE/P INVERTER
The inverter continuously adjusts the rotation speed of the electric pump, keeping the pressure constant, even when the flow rate varies.
The other electric pumps, also with variable speed, are activated in cascade after the first one has reached maximum speed. Through modulation, they compensate the pressure fluctuations of the system.
For every operating cycle, it is possible to switch the restart to a different pump, therefore ensuring even use of all electric pumps.
It is possible to set operation times for each individual pump, switching to another pump after such set times.
The "SP" pressure can be adjusted by the user using the "+" and "-" keys found on the MCE/P (as a rule, all the pumps are set to the same pressure value). With the new MCE/P, it is sufficient to set the data on one of the devices, and it will be automatically propagated to the other pumps of the system.
