Overview

The Triad Magnetics WSU060-2500-13 is a wall plug-in switch mode power supply delivering a regulated 5.9 V DC output at up to 2.5 A, with center negative polarity. It accepts a universal 90 to 264 V AC input across 50 and 60 Hz mains frequencies, making it suitable for global deployment. The output connector is a barrel plug with a 5.5 mm OD and 2.5 mm ID. This supply is designed for applications requiring a compact, externally mounted regulated DC source, removing the need for an internal power supply within the end product.

Locating power conversion outside the end product removes a source of heat and audible noise from the immediate product environment - a practical benefit for thermally or acoustically sensitive designs. Output voltage is regulated to ±5% load and line regulation, and ripple and noise are specified at a maximum of 150 mV pk-pk. Standby power draw is less than 100 mW, and average efficiency meets or exceeds 82.39%, satisfying Level VI efficiency requirements under EISA 2007/CEC. The fully enclosed thermoplastic molded enclosure prevents user access to internal components. Over-voltage and short-circuit protection are incorporated.

The unit ships with a 5 ft, 18 AWG output cord and carries UL 62368-1 Class II, Double Insulated certification (UL File E345519) along with FCC Part 15 Subpart B and ICES-003 Issue 6 EMI compliance. The product meets RoHS 3 (2015/863/EU) requirements as of February 2016. Before selection, designers should confirm the center-negative polarity matches the load's input requirements, verify that the 5.5 mm/2.5 mm barrel connector matches the mating receptacle, and ensure the operating temperature range of 0 to 40 °C suits the intended environment.
