Kewell A2000 Series Bidirectional AC Source
A2000 Series is a bi-directional programmable AC power supply featuring high accuracy, high dynamic response, and high efficiency. The series adopts SiC design of the third-generation wide bandgap semiconductor devices, allowing it to be modularized and standardized, offering industry leading performance and experience. A2000 Series supports waveform editing, harmonic/inter-harmonic injection, RLC load and other functions, with built-in standard curves of different countries to meet the testing requirements of various industries.
The Kewell A2000 series is a family of bidirectional AC sources in the power range between 45 and 225 kVA. The output voltage is 450 VAC, the maximum current in the range between 90 and 340 A (high voltage 100...500 kW, 0...900 V, 0...500 A). The sources are suitable for AC grid simulation, for example when testing PV and wind power inverters, energy conversion systems, charging stations and OBCs. The devices in the series are available in two versions (PG) and (UG) .
