The OWON OWH67B Series integrates source and load functions with seamless bidirectional operation. In source mode, the instrument supports constant current (CC), constant voltage (CV), and constant power (CP), while load mode supports constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP). The OWH67B018-60 provides an output voltage range of 0–60V, an output current range of -120A to 120A, and a bidirectional power range of -1.8kW to 1.8kW. It offers 10mV/10mA setting and readback resolution with voltage setting and readback accuracy of ≤0.05% + 0.05%FS. The instrument includes seven high-fidelity battery characteristic models for battery simulation and supports photovoltaic simulation using SAS models such as EN50530 and Sandia. A built-in bleed circuit helps eliminate residual high voltage after shutdown. With OVP, OCP, and OPP protection, a 3.95-inch TFT LCD, USB, LAN, and RS485 interfaces, and SCPI support, the OWH67B is suitable for laboratory, industrial, and automated testing applications.
