Key terms
- Bidirectional / dual-quadrant
- A supply that both sources and sinks current, switching seamlessly between charge and discharge.
- Regenerative load
- An electronic load that returns absorbed energy to the grid instead of dissipating it as heat — here up to 93%.
- CC / CV / CP / CR
- Constant current / voltage / power / resistance operating modes, with CC&CV priority to protect the DUT.
- F.S. accuracy
- Accuracy stated as a percent of reading plus a percent of full scale (e.g. 0.02% + 0.02% F.S.).
- EN 50530 / Sandia
- Standard static and dynamic MPPT efficiency profiles for PV inverter testing via a solar array simulator.
- SCPI / Modbus-RTU / CANopen
- Automation protocols over LAN/RS232/RS485/CAN for ATE integration.
