DGM

From the Bonfiglioli experience comes DGM, the new range of decentralized inverters for the control of asynchronous motors. DGM is perfect for the pump, ventilation and process industries thanks to the PID control, the high number of on-board I / O (digital and analog) and the integrated Soft Plc as standard for stand-alone applications. DGM 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.

Key benefits

Application switchboard volume and cooling system reduction
Streamlined and simpler plant design.
Plant extensibility not affected by switchboard capacity.
No expensive shielded power cables required (otherwise necessary to meet the EMC standards).
Possibility of remote control thanks to the wide availability of digital and analog inputs and outputs and available field buses.
