Overview
The UNI-T UDP3305S is a 4-channel programmable linear DC power supply with 1 mV / 1 mA setting resolution, 328W total output, and full automation-grade connectivity — USB-Host, LAN, RS-232, and Digital I/O. CH1 and CH2 deliver 0–30V at up to 5A independently or in software-routed series (up to 60V) or parallel (up to 10A) without external wiring. CH3 provides a 0–6V/3A logic-level channel. The linear topology holds output ripple under 350 µVrms (5 Hz–1 MHz) — clean enough for sensor-bridge excitation, ADC reference rails, and any work where switching-supply artifacts would land in the measurement budget.
For embedded prototyping, sensor characterization, automated test integration, and R&D workflows where 1 mV setpoint precision matters, the Performance Series tier is the target configuration of the UDP3000S platform. The 4.3-inch TFT displays voltage, current, and power waveforms in real time across all configured channels — transient load behavior, inrush events, and power-up sequences are visible at the supply itself, no oscilloscope required for routine power-behavior observation.
