UNI-T UTP3305C 315W Programmable Linear DC Power Supply – 3 Channel, 2× 0–30V / 0–5A + 5V/3A Fixed, Series & Parallel, USB & RS-232
UNI-T UTP3305C — a 315 W programmable linear DC power supply from the UTP3300C series, with two independent 0–30 V / 0–5 A channels plus a fixed 5 V / 3 A logic supply. Linear regulation holds ripple to ≤2 mVrms, so it suits sensitive analogue and RF work where switching noise is unacceptable. Series and parallel modes, five memory groups, power-off memory and USB / RS-232 remote control make it a strong fit for R&D, production test and teaching labs. Genuine UNI-T product supplied by Digilog.pk with manual and warranty.
Key Features
