UDP4303S 4Ch 297W 32V/10A Programmable Linear DC Power Supply
Product Details
UPC: 6935750543139
Manufacturer: UNI-T
Warranty: 3 years

Equipment Type: DC Power Supply
The UDP4303S is a four-channel precision programmable linear DC power supply with 297 W total output and fully isolated channels: CH1 and CH2 at 0–32 V / 3 A, CH3 at 0–15 V / 3 A, and CH4 at 0–6 V / 10 A. Linear regulation holds output ripple under 350 µVrms, and a low-current mode resolves down to 1 µA across all channels for IoT, sensor, and battery-drain testing.
Output sampling at 8 kSa/s drives a real-time voltage/current/power waveform display, and 1 ms programming-time resolution supports arbitrary waveforms via a 512-group list with sine, ramp, and pulse templates. CH1 and CH2 combine for up to 64 V in series or 6 A in parallel, with four-wire remote sense on all channels, a controllable bleeder circuit, and configurable OCP (0–10 s delay, under 3 ms fastest).
Remote control is provided over USB, LAN, and RS-232 with SCPI, a web-browser interface, and digital trigger I/O, suiting it to precision analog, sensor, and automated test work.
