Overview

The OWON SPE Series High Voltage DC Power Supply is available in multiple voltage and current configurations, supporting output voltages from 0 to 150V, 300V, or 500V and power levels up to 500W. The series provides precise digital control with voltage and current setting and readback resolution down to 10mV and 1mA. CV and CC operating modes allow stable voltage or current regulation for different testing requirements. Built-in OVP, OCP, and OTP protection helps protect both the power supply and connected equipment. The programmable list waveform function supports up to 10 timing steps, while four memory presets allow frequently used settings to be recalled quickly. The SPE Series can also be controlled through PC software and supports USB, optional RS232/RS485, and optional LAN interfaces with SCPI and Modbus communication protocols, making it suitable for automated test systems and centralized industrial control.
