61845

45kVA Single / Three-Phase Regenerative Grid Simulator Providing a Complete Energy-saving Solution

The Chroma 61845 Regenerative Grid Simulator is a full 4 quadrant, full 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 Chroma 61845 is designed to simulate grid characteristics for testing PV inverter and on-line UPSs. 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 recycle it back to the grid.
