UDP3303C 3Ch 195W 30V/3A Programmable Linear DC Power Supply

The UDP3303C is the SCPI-programmable version of the three-channel 195 W linear platform. CH1 and CH2 are adjustable from 0–30 V at 0–3 A, and a third channel switches between fixed 1.8 V, 2.5 V, 3.3 V, and 5 V logic rails at 3.2 A; linear regulation holds output ripple under 1 mVrms.

CH1 and CH2 combine in series for up to 60 V or in parallel for up to 6 A from the front panel, with a master-slave tracking mode for matched dual-rail testing. Each channel offers 10 mV / 1 mA setting resolution on a 4-digit display, with configurable per-channel OVP/OCP, over-temperature shutdown, keypad lock, and five preset memory groups. A front-panel 5 V / 2 A USB-A port provides charging power.

Remote control is provided over USB-Device or RS-232 with a full SCPI command set (voltage programming accuracy ≤0.1% + 30 mV, current ≤0.5% + 2 mA), suiting it to automated sweeps, sleep-mode current characterization, and bench prototyping.
