We’re not kidding when we say the SPD3303C is no joke – it’s seriously solid gear. You’ve got two full adjustable channels (32 V/3.2 A each) and a third fixed one with 2.5 V, 3.3 V, or 5 V at 3.2 A. Total of 220 W of clean, linear power, with ultra‑tight regulation (≤ 1 mV noise), short‑circuit and overload protections, and the option to run in independent, series, or parallel mode. The turn‑knobs plus pushbuttons and bright LED screen make dialing in settings easy, and building quality feels hefty (a toroidal transformer inside delivers reliable performance). The fan is smart and quiet, so you get performance without the racket.
