Pump Inverter IMTP2.2 M-RS For onboard motor mounting and RS485 communication system

Pump-Inverters Series offers versions of inverters for onboard motor mounting type installation that allow to set up in series the most compact, professional and industrialized booster sets of the highest level

The pressurization systems set up from groups of more pumps with inverters for onboard motor installation in with each inverter is fitted on its correspondent pump. All the variable speed drives communicate each other through radio type Blue Connect or through serial cable RS485, adapting to vertical and horizontal surface pumps.

  • Single-phase inverter voltage supply 1x (100-244)V
  • Three-phase inverter voltage output 3x (100-244)V
  • Maximum motor-pump power up to 2.2 kW
  • Maximum output current 9.5A
  • Nominal motor frequency from 50 to 140 Hz
  • Pressure measure range 0-30 bar
  • Communication with other inverters by RS485 communication system
On the models for installation directly on the motor there are always present output relays or in DC Voltage to drive an on-off switch that can control a second ON-OFF pump: such a system needs therefore that one pump is driven by an inverter and the second pump ON-OFF.

The inverter control logic, when the water demands increases, determinate, thanks to an optimized algorithm, the right moment to enable the second pump without creating any sudden pressure drop, then, when water demands decreases, it’ll determine the right moment to disable the second pump without creating pressure peaks on the delivery side manifold.
