The OWON OWH6522 provides a single programmable DC output with a rated range of 0–60V and 0–120A, delivering up to 3000W of output power. The instrument provides 10mV voltage and 1mA current setting and readback resolution, with voltage setting and readback accuracy of ≤0.05% ± 30mV. Selectable CV/CC priority modes allow the power supply to adapt to different load characteristics. Up to 100-step LIST sequence programming enables automated output sequences and PC-controlled testing. The built-in P-V curve simulation function can simulate solar panel I-V characteristics for photovoltaic testing. The power supply also integrates OVP, OCP, and OPP protection and provides USB, LAN, and RS485 communication interfaces with SCPI compatibility. A 3.9-inch TFT LCD provides real-time viewing of dynamic waveforms and test parameters, while the 2U form factor allows installation in standard 19-inch racks.
