Overview
The WSU050-1500-R13 is a switchmode wall plug-in power supply from Triad Magnetics. It delivers a regulated 5.0 V DC output at up to 1.50 A, with a maximum power output of 7.50 W. It accepts a universal 100 to 240 V AC input and operates across both 50 Hz and 60 Hz mains frequencies, making it compatible with a wide range of international markets. The output connector is configured as center negative, with a barrel plug measuring 5.5 mm OD and 2.5 mm ID.
The regulated switchmode design keeps output voltage stable under varying load conditions, removing the need for internal power supply circuitry in the end product. The wall plug-in form factor keeps heat away from sensitive circuits and reduces acoustic noise and size requirements within the end product. The unit is fully enclosed to prevent user access to internal components, supporting safe deployment in consumer-facing and light industrial applications. Its Level VI EISA 2007 efficiency rating confirms compliance with energy efficiency requirements for external power supplies.
The supply is housed in a compact case measuring 2.67 in x 1.81 in x 1.37 in (67.70 mm x 45.90 mm x 34.80 mm). Before selecting this unit, designers should confirm that the center-negative barrel plug polarity and the 5.5 mm OD / 2.5 mm ID connector dimensions are compatible with the target equipment's input jack. Verify that the 7.50 W maximum output is sufficient for the intended load, and confirm that the cord length meets the installation requirements of the specific application.
