+ Supports 100-step LIST waveform programmable output
+ Selectable CC/CV Priority with smooth startup and no overshoot, adaptable to different load conditions.
+ Built-in discharge circuit to eliminate residual high voltage when power is turned off
+ Equipped with USB, LAN, and RS485 interfaces, supporting SCPI and Modbus protocols separately. Enables real-time monitoring, flexible output configuration, and easy integration into automation systems.
+ Supports photovoltaic simulator output function, embedded with EN50530, Sandia and other PV standard curves for direct evaluation of PV inverter MPPT efficiency (optional)
+ 3.95-inch TFT display provides real-time, intuitive visualization of voltage/current waveforms and parameters, making power status monitoring clearer and safer.
The OWH67D Series is a dual-channel high--power programmable DC power supply that supports wide-range constant power output. It includes models OWH67010D-80 (80V/20A,1000W),
OWH67060D-600(600V/10A,6000W), OWH67060D-150 (150V/30A,6000W) and
OWH67060D-300(300V/15A), covering diverse high-voltage and high-current testing applications.
Equipped with a 3.95-inch color LCD display, the OWH67D offers a user-friendly interface and excellent performance, with a minimum setting resolution of 10mV / 1mA.
lt delivers high-precision, stable, and reliable output, with selectable CC / CV priority, programmable LlST waveform output, and a built-in discharge circuit. Comprehe nsive protections include adjustable
OVP, OCP, OPP, input undervoltage, and internal short-circuit protection. Beyond power output, it also provides measurement capability and supports PV simulator functions with built-in EN50530 and Sandia curves for direct evaluation of PV inverter MPPT efficiency.
The OWH67D series comes with standard LAN /RS485 / USB interfaces, supporting SCPl and Modbus protocols. It allows remote control via USB communication for real-time monitoring and flexible output co
onfiguration. It is widely used in power design validation, general laboratory testing, automotive electronics, and new energy applications.
