Home | Old Products | DKG-727 Mains Parallelling Unit


The DKG-727 is a comprehensive automatic paralleling with mains unit for multiple generating sets, featuring Manual and Automatic Load transfer between mains and multiple generating sets operating in parallel.

Up to 7 generating sets may be paralleled with mains using DKG-727 units without the need for extra modules. The communication between modules is made with the Datalink connection.



In automatic position, DKG-727 monitors mains phase voltages and controls the automatic starting, stopping and load transfer of the generating sets in case of a mains failure.

In case of mains failure DKG-727 energizes the remote system start output and waits until the sufficient number of generating sets to supply the programmed prime power are started, synchronized and closed to the busbar. Once the ready signal input is applied, the DKG-727 transfers the load to the busbar.
