The 61800 Regenerative Grid Simulator is a full 4 quadrant, fully regenerative, AC power supply designed for common electrical product testing such as home appliances, and industrial electronics needing a programmable input source. In addition, the 61800 is designed to simulate grid characteristics for testing PV inverter and on-line UPSs. As shown below, power can be both sink and source from the UUT seamlessly to support different types of applications. In cases where the UUT sources current a detection circuit will sense the excess power and recycled it back to the grid.
