Power Supply for 12 V Devices

This EPS switching power supply delivers a regulated 12 V output at up to 3 A. It accepts an AC input range of 100 to 120 V at 50 to 60 Hz. The unit uses a 2.1 mm barrel connector for DC output. It is intended as a direct replacement or spare adapter for compatible equipment.

Suitable for Matching Barrel Jacks

This adapter suits hardware that requires exactly 12 V DC at 3 A with a 2.1 mm centre-positive plug. Buyers whose devices need a different voltage, a higher current rating or a different connector diameter should look at other models. The fixed 100 to 120 V AC input also makes it unsuitable for regions where mains voltage exceeds 120 V.

Output Fixed at 12 V 3 A

The single specification that determines fit is the 12 V 3 A DC output on a 2.1 mm barrel jack. If the target device specifies the same voltage, equal or lower current draw and the same plug size, this supply will power it. Any mismatch in voltage, polarity or connector dimensions means this unit cannot be used.
