Stamos Soldering S-LS-28 power supply teardown

This is a quick review on Stamos Soldering S-LS-28 laboratory power supply. The internal components used made me suspicious and I figured out that Korad KD3305D is virtually identical to this model. The 550W dual power supply has two 0-30V, 0-5A DC channels and a third channel for 2.5, 3.3 or 5 V, max 3A.
