DGM Modular
Decentralized inverter
From the Bonfiglioli experience comes DGM Modular, the new range of decentralized inverters for the control of asynchronous & Reluctance synchronous motor control. DGM Modular is perfect for Packaging and Logistic Sectors, thanks to various Option and It's optimal quality-price ratio. DGM Modular can be supplied combined with a gearmotor or separately, for wall or on-board motor mounting. When the inverter is supplied with the gearmotor, mechanical assembly, wiring and basic programming are performed by Bonfiglioli, thus reducing installation times, limiting the risk of errors. Design and installation are faster than inverters installed in classic centralized switchboards and, by decentralizing the control, it is possible to minimize the size of the panel itself.


  • The power is distributed in the different enclosures according to the following table:

    Series - Frame size | kW

    DGM-MPM - A | 0.55
    DGM-MPM - A | 0.75
    DGM-MPM - A | 1.1
    DGM-MPM - A | 1.5
    DGM-MPM - A | 2.2 low duty
    DGM-MPM - B | 2.2
    DGM-MPM - B | 3.0
    DGM-MPM - B | 4.0
    DGM-MPM - B | 5.5 low duty
    DGM-MPM - C | 5.5
    DGM-MPM - C | 7.5
    DGM-MPM - C | 11.0 low duty
    DGM-MPM - D | 11.0
    DGM-MPM - D | 15.0
    DGM-MPM - D | 18.5
    DGM-MPM - D | 22.0
    DGM-MPM - D | 30.0 low duty
