In the testing field of PCS inverters, we can provide the following product testing solutions:
Programmable bidirectional DC power supply: It can simulate solar cells, and can also be used as a load to realize the integration of source and load, while absorbing power and returning it to the grid cleanly.
Feedback grid analog power supply (AC source): It can simulate various working conditions such as grid voltage, frequency fluctuation, unbalanced output, etc. It can inject harmonics and inter-harmonics, absorb power and return it to the grid cleanly.
High-precision power analyzer: It can measure conventional parameters such as input and output voltage, current, and power of PCS inverters in multiple channels, as well as harmonic distortion and harmonic content of each order.
Safety performance comprehensive analyzer (safety tester): Wide range and high precision, 10kV AC and DC withstand voltage/insulation and 100A DC grounding test, meeting the comprehensive safety test of PCS components and inverters.
Oscilloscope: It can measure input and output waveforms in multiple channels, monitor the output quality of PCS inverter, frequency, THD and other parameters.
