Advantages of the DG1 Series VFD
Unlike the traditional VFD system, Eaton’s DG1 line of VFDs have onboard controllers to eliminate the need and the cost for separate PLCs. The DG1 ties the VFDs together via Ethernet and identifies one to be the master controller. All the installer has to do now is set the application parameters. The master VFD acts as a PLC and comes pre-programmed to manage the networked devices to achieve the specified output.
VFDs in Action
For example, in a water lift application in high rise apartments, the penthouse needs the same water pressure in their shower as the first-floor apartment. To do this, you need variable output pumps working together. The DG1 series of Eaton VFD can handle this with ease. Simply place pressure sensors at key points in your building, tie them back to your master VFD, set the target pressure and let the VFD network do the rest.
During peak hours when water demand is high, the VFD will sense the need and activate the right number of pumps at the right output to maintain the target water pressure. During off-peak times, the VFD ramps down output, or completely deactivates, so the pumps meet the lesser demand, no more, no less. The DG1 can even be programmed to rotate the use of the pumps so they wear evenly.
