The OWON OWH80Q Series provides four-channel programmable DC output with models covering different current and power levels. The series supports up to 80V output and up to 20A per channel, with configurations offering 600W, 1000W, or 2000W total output power. Its fanless design provides quiet operation while the power supply uses a high-performance heat dissipation design. With 10mV/1mA setting and readback resolution and up to 0.05% accuracy, the series is suitable for applications requiring precise programmable DC power. CV/CC priority control enables adaptation to different load characteristics, while the built-in bleed circuit helps eliminate residual high voltage after shutdown. The 3-inch TFT LCD provides output curve visualization and online one-minute data logging. LAN, RS485, and RS232 interfaces with SCPI support enable remote programming, monitoring, and integration into automated test environments.
