On mains failure and receiving generator power, it connects the load to DG supply. During DG operation, load drawn is monitored. If the load exceeds the allotted limit, it disrupts the supply and rechecks in intervals. On reducing the load and keeping it within the limit, load is connected to DG supply. For different applications, we have specific models. They are with load limiter, without load limiter, transfer of load from one phase to other phase and many additional functions.
