描述

9129B is a triple output programmable linear DC power supply featuring three independent and electrically isolated outputs that can be adjusted independently or combined in series or parallel for higher voltage or current. It provides voltage outputs of 0–30 V on CH1 and CH2, and 0–5 V on CH3, with current capability of 0–3 A on all channels and a total power rating of 195 W. The supply offers low noise linear regulation with voltage ripple = 5 mVp-p and load regulation = 0.02 % + 4 mV, along with overvoltage (OVP) and overtemperature (OTP) protection. Remote control is enabled via USB interface supporting SCPI commands, and up to 27 instrument settings can be stored and recalled. This power supply is suitable for education, service, and electronic design applications where multiple isolated outputs and precise voltage/current control are required.
