Overview

The OWH67D Series provides two independently controllable DC output channels in a compact 2U rack-mounted design, with both front and rear panel output connections. The series includes the OWH67010D-80 with 80V/20A output and 1000W constant power, as well as the OWH67060D-150, OWH67060D-300, and OWH67060D-600 models supporting up to 6000W constant power. The power supply provides 10mV/1mA setting and readback resolution and high-precision output control of up to 0.05%. Selectable CC/CV priority modes enable smooth startup without overshoot and allow the instrument to adapt to different load characteristics. Up to 100-step LIST waveform programming supports automated testing. The optional photovoltaic simulator function includes EN50530, Sandia, and other PV standard curves for evaluating PV inverter MPPT efficiency. Comprehensive protection includes OVP, OCP, OPP, input undervoltage, and internal short-circuit protection. USB, LAN, and RS485 interfaces provide remote monitoring and control with SCPI and Modbus protocol support.
