Overview

The OWON SPS Series Fanless Single Channel Programmable DC Power Supply provides stable and precise DC power while eliminating the noise and potential reliability issues associated with traditional cooling fans. The series includes models with output ratings from 30V to 80V and currents from 5A to 8A, with power ratings up to 150W. Voltage and current can be set and read back with resolutions of 10mV and 1mA respectively. The power supply supports constant voltage and constant current operation, programmable list waveform editing and output, and four groups of memory presets for quickly recalling frequently used settings. Integrated over-voltage, over-current, over-temperature, and input undervoltage protection helps safeguard the instrument and connected devices. A built-in discharge circuit reduces residual high-voltage risks after the output is switched off. USB communication and SCPI support enable PC programming, remote control, and integration into automated test systems.
