The OWON OWH67 Series provides high-power constant-output capability from 1200W to 6000W across a wide range of voltage and current configurations. Models include the OWH67012, OWH67018, OWH67020, OWH67030, and OWH67060 series. The power supplies accept 85V–265V AC input and provide high-resolution 10mV/1mA setting control with 1mV/1mA readback resolution. CV and CC priority modes support adjustable rise and fall times for controlled startup and dynamic testing. The series supports up to 100-step LIST waveform programming for automated output sequences and includes a built-in discharge circuit for the output. For renewable-energy testing, the optional photovoltaic simulator supports EN50530, Sandia, and other PV standard curves. Analog I/O and dry-contact functionality provide additional integration options for automated systems. A 3.9-inch TFT LCD displays voltage and current curves in real time and supports online recording of one-minute data. Communication options include USB, RS485, CAN, DB25, and optional LAN, with SCPI support for remote control and automation.
