The UDP3305S-E is the education variant of the UDP3000S Performance Series 328W four-channel programmable linear DC supply. CH1/CH2 each provide 0–30V/5A, CH3 provides 0–6V/3A, and CH4 is a 5V/2A USB output. Its 10mV/1mA setting resolution suits electronics teaching labs, general R&D benches, and automated testing. The 4.3-inch TFT plots voltage, current, and power in real time, while one-key CH1/CH2 series operation reaches 60V and parallel operation reaches 10A. USB, LAN, RS-232, Digital I/O, SCPI, and the built-in web server simplify multi-station and scripted workflows.
