OWH6546 Series High Voltage Programmable DC Power
+ Designed for high-voltage, high-power applications (18kW/1200V/30A, three-phase input), delivering 0.05% ultra-high precision control for long-term stability and low thermal drift
+ 10mV / 1mA setting and readback resolution
+ Selectable CV/CC priority mode to flexibly adapt to different load characteristics
+ Supports up to 100-step LIST sequence programming and PC remote control
+ Built-in P-V curve simulation to accurately simulate solar panel I-V characteristics
+ Fully digital control with integrated OVP, OCP, and OPP protections
+ Standard USB CDC, RS485, and Ethernet interfaces; SCPI compatible
+ 3.9-inch TFT color display for real-time viewing of dynamic waveforms and test parameters
