New High Power Regenerative Grid Simulators Test On-grid Products from Chroma

Chroma Systems Solutions, Inc.  announced the release of their 61800 Regenerative Grid Simulator. The 61800 is a full 4 quadrant, fully regenerative, AC power source with advanced features satisfying rigorous regulatory standards testing as well as design and verification testing throughout the product development cycle. The 61800’s power can both sink and source from the UUT seamlessly to support countless applications. In cases where the UUT sources current, a detection circuit will sense the excess power and recycle it back to the grid. Designed to simulate grid characteristics the 61800 is ideal for testing PV inverter, on-line UPS, Smart Grid, Vehicle to Grid (V2G) and Energy Storage System (ESS) applications as well as common electrical product testing such as home appliances and industrial electronics requiring a programmable input source.

The 61800 Regenerative Grid Simulator is currently offered in two models: 45kVA and 60kVA. Its extensive feature set boosts state-of-the-art digital control technology and can deliver up to 300VAC at output frequencies ranging from 30Hz to 100Hz. The AC+DC feature allows for applications that require a DC offset bias. In addition to supplying clean, precise and stable AC voltage, the 61800 is capable of simulating various types of distorted voltage waveforms and transient conditions required by product validation testing.
