Summary


C3000H series is a high performance, programmable DC power supply developed by Kewell. It supports high DC voltage output with IV simulation. IV simulation adopts self-developed core control strategy to ensure high-precision output and high dynamic characteristics. The series is mainly used to test the MPPT efficiency of inverters, overcoming the challenge in testing and tracking the performance of high-power PV inverters.
