Overview
The UNI-T UDP4303S is a 4-channel, 297W precision programmable linear DC power supply with fully isolated outputs: two 0–32V/3A channels, one 0–15V/3A channel, and one 0–6V/10A channel. The linear topology delivers exceptionally clean output with ripple under 350 µVrms — critical for sensitive analog circuits, precision sensor development, and any application where switching noise is unacceptable.
With 8 kSa/s output sampling across all four channels, 1 µA current resolution, 1 ms programming time resolution, and a built-in waveform display, the UDP4303S provides real-time visibility into transient load behavior that competing supplies simply cannot match. Series/parallel/tracking modes, a controllable bleeder circuit, and comprehensive OVP/OCP/OTP protection round out a professional-grade instrument (3 years standard + 2 with free registration = 5 years total).
