Description
Overview
The GW Instek GPS-4303 is a four-channel linear DC power supply delivering 200W across independent isolated channels. Channels 1 and 2 provide variable 0–30V/0–3A output with tracking capability, while Channels 3 and 4 supply fixed auxiliary voltages (2.2–5.2V and 8–15V respectively, 1A each). All channels feature high regulation (0.01%) and low ripple/noise, designed for multi-rail systems requiring both primary and auxiliary power sources.
