All in one unit
IT7900P series integrates 3 products, a grid simulator (IT7900), an AC/DC power supply (IT7800) and a regenerative AC/DC load (IT8200).
4-Quadrant output
IT7900P series is not only a full four-quadrant power grid simulator, but also a full four-quadrant AC/DC electronic load. It can operate in all four quadrants. The efficient energy regeneration function makes it good for testing the frequency change of grid-connected PV inverters, voltage transients and anti-islanding protection.
Professional Anti-islanding Test Mode
To meet the certification test of anti-islanding effect for grid-tied products, the IT7900P series provide a professional anit-islanding test mode. Users can adjust RLC parameters or configure the parameters of active power and reactive power to achieve the effect of simulating purely resistive or nonlinear grid loads, and further verify the anti-islanding protection response time of grid-tied DUTs under different equivalent impedances, three-phase load balancing and non-balancing conditions. The solution helps engineers to simplify the test circuit and cost savings of additional equipment such as RLC load and power meter.
The IT7900P series high-performance Regenerative grid simulator provides an all-in-one test solution that can be used not only as a grid simulator and four-quadrant power amplifier, but also as a four-quadrant regenerative AC/DC electronic load.
The full four-quadrant operation, regenerative ability can feedback power to the grid, meet the needs of environmental protection, but also save a lot of electricity and heat dissipation costs. Compact, modular and efficient structure design allows the IT7900P up to 15kVA in 3U single unit, and its power can be extended to 960kVA after master-slave parallel connection. Colorful touch screen with intuitive GUI allows IT7900P to directly define different waveforms. The rich operation modes can meet the test requirement of single-phase, three-phase, inverse-phase and multi-channel. It provides high flexibility for testing and can be used in many applications such as PV, ESS and EV.
