Aikesaibo programmable bidirectional regenerative AC source/load - grid simulator PRE20 series

The PRE20 series regenerative programmable AC source-load integrated machine features both AC power source and AC load functions. Its integrated source-load design concept once again leads the development direction of a new generation of AC power sources. The matrix parallel function configured in the PRE20 series products can be expanded in parallel up to 200kW, meeting the needs of both small size (3U/20kW) and large capacity. The PRE20 series products have four-quadrant operating capability; as a power source, they can meet the general grid adaptability regulatory test requirements, and as an RLC load, they can meet the anti-islanding protection performance test requirements of the new energy industry and off-grid load requirements. No optional accessories are needed to achieve dual use in one machine, and 100% of the current can be recycled back to the grid, with a regenerative efficiency of up to 91%.
