What this adapter powers

The Phihong PSC15R-050 delivers 5 V at 3 A through a 5.5 mm barrel connector with negative centre polarity. It is a 15 W AC adapter intended for devices that match this exact voltage, current and plug specification.

Input range and plug fit

The unit accepts 100-240 V at 50-60 Hz, so it works on mains supplies worldwide. Only equipment that requires a 5.5 mm by 2.1 mm barrel plug with the stated polarity can be connected safely.

Check your device before ordering

Verify that your hardware specifies 5 V input, draws no more than 3 A and uses a 5.5 mm barrel jack with negative centre polarity. Do not use this adapter if your device needs a different voltage, higher current or an alternative connector type.

Questions about this item

Which capacity should I pick for a device that needs 5 V at 3 A?

The single 5 V 3 A 15 W model matches that requirement exactly.

What does the 15 W rating mean when the adapter is powering my hardware?

It can supply up to 15 W continuously at 5 V, so the connected device must draw 3 A or less.

What connector standard does the 5.5 mm barrel use and what does it limit?

The 5.5 mm by 2.1 mm centre-negative barrel plug fits devices wired for that polarity and size.
