YH 1502D+ USB DC Power Supply
The YH 1502D+ USB DC Power Supply is an ideal benchtop companion for electronics labs, mobile phone repair, and general prototyping.
With wide 110–240 V AC input, this lightweight unit provides precisely adjustable 0–15 V, 0–2 A output plus a fixed 5 V USB port. Dual LED displays show voltage and current in real time, while coarse and fine knobs allow accurate tuning. The automatic constant-voltage/constant-current feature provides stable delivery and built‑in over‑current, short‑circuit, and thermal protection, adding safety to your workbench.
Applications include smartphone and USB device repair, LED testing, battery charging, and powering Arduino/Raspberry Pi projects. It’s especially helpful for school labs, repair shops, and production lines.
