Universal AC Test Power Supply
Main Features
Dual-Mode Source and Load Integration
Combines AC power supply and regenerative AC load functions in one device, supporting both grid compliance testing and anti‑islanding protection or off‑grid load simulation without additional accessories.
Four-Quadrant Operation and High Energy Recovery
Enables bidirectional power flow with up to 91% regenerative efficiency, feeding up to 100% of the absorbed current back to the grid to minimize energy waste during testing.
Wide Industry Application
Suitable for grid‑adaptability regulatory tests as a power supply, as well as for new‑energy industry applications such as inverter anti‑islanding validation and off‑grid load performance evaluation.
A Test Power Supply is a specialized, high-precision electrical device designed to provide controllable, adjustable, and stable electrical energy for testing, verifying, and validating the performance, reliability, and compliance of electrical equipment, power components, and electronic systems.
The PRE Series Universal AC Test Power Supply is a new-generation regenerative programmable AC source-load integrated device, featuring both AC power supply and AC load functions.
With four-quadrant operation capability, this series can meet general grid adaptability regulatory testing requirements when used as a power supply, and satisfy anti-islanding protection performance testing and off-grid load demands in the new energy industry when functioning as an RLC load.
It achieves dual-purpose operation without the need for any optional accessories, enabling 100% current recycling to the power grid with a regenerative efficiency of up to 91%.
