The OWON SPX Series provides single-channel programmable DC power in a compact form factor suitable for bench and testing environments. The series includes models ranging from 300W to 500W, with output configurations up to 60V and 20A. Wide-range constant power output allows flexible voltage and current combinations within the rated power range. The power supply provides 10mV/1mA setting and readback resolution and simultaneously displays set values, measured values, and real-time output power. Automatic CC/CV switching helps adapt the supply to changing load conditions, while OVP, OCP, and OTP protection provide additional safety. Intelligent fan speed control balances cooling performance with operating noise, and three preset parameter memories allow frequently used configurations to be recalled quickly.
