Overview

The OWON OWH80 Series DC Power Supply is designed for high-power DC testing and power applications requiring stable and accurately controlled output. The series offers three models: OWH80120-1800 with 0–80V/0–120A/1800W, OWH50120-1800 with 0–50V/0–120A/1800W, and OWH8080-2000 with 0–80V/0–80A/2000W. The supplies provide 10mV/1mA setting resolution and 1mV/1mA readback resolution, with voltage accuracy up to 0.05%. CV/CC priority settings allow the output behavior to be adapted to different load characteristics. A built-in bleed circuit helps eliminate residual high voltage after shutdown, while OVP, OCP, and OPP protection provide additional operating safety. The 3-inch TFT LCD supports curve display and online one-minute data logging. LAN, RS485, and RS232 interfaces provide remote communication and integration capabilities with SCPI support.
