The OWON OWH6546 Series provides a single high-voltage programmable DC output with a maximum voltage of 1200V. The OWH6546 delivers up to 30A and 18kW, while the OWH6546A provides up to 20A and 12kW. Both models use a 3-phase, 4-wire 380Vac ±10% input and provide 10mV/1mA setting and readback resolution. Selectable CV/CC priority modes allow the power supply to adapt to different load characteristics. Up to 100-step LIST sequence programming supports automated testing and PC remote control. A built-in P-V curve simulation function enables simulation of solar panel I-V characteristics for photovoltaic applications. The unit also integrates OVP, OCP, and OPP protection and provides USB, LAN, and RS485 interfaces with SCPI compatibility. A 3.9-inch TFT LCD provides real-time viewing of dynamic waveforms and test parameters.
