Chroma model 61830/61845/61860/61800-100/61800-100(800VLN) Regenerative Grid Simulator
Market demand for Distributed Resource (DR) products such as PV inverters and wind energy systems is steadily growing as the world strives for clean renewable energy sources. This demand has created a need for rigorous regulation testing to standards like UL 1741SA / IEEE 1547 / IEC 62116 which ensure proper and safe operation of on-grid products. It has become critical to manufacturers to conduct these tests in order to prove compliance and to relieve product liability concerns. Chroma's new 61800 family of Grid Simulators has been designed to fulfill these test requirements by providing a full 4 quadrant, fully regenerative, grid simulator with advanced features for compliance, safety and product verification testing.
Functions and Applications
The 61800 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 additional, 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.
