Linear Wall Plug-In Power Supplies For Industrial And Commercial Applications

Design engineers looking for linear external wall plug-in power supplies to support commercial or industrial equipment will find the WAU AC Series and WDU DC Series Power Supplies from Triad Magnetics provide low to zero noise performance along with high reliability and longer life than switching power designs.

Triad’s WAU AC Series Wall Plug-In Power Supplies combine the performance advantages of a linear design with the reliability benefits of a low component count device. They also eliminate the need for an internal power supply’s cooling device, thereby reducing the noise level, size and weight of the end product. These compact power sources with generous 6-foot cords keep heat away from sensitive circuits and supply a safer lower output to the end product.

The WAU AC Series Wall Plug-In Power Supplies from Triad feature a 60 Hz, 120V input design, which is completely enclosed to prevent tampering. They are offered in a wide range of popular output voltages: 12, 16, 20 and 24 Vac. Input power ranges available are from 4 to 52.2 W. With their extensive agency approval listings, their use also aids in speeding up the agency approval process.

Like their cousins, Triad’s WDU DC Series Wall Plug-In Power Supplies combine advanced linear design with the benefits of reduced noise levels, smaller physical sizes and trimmer weights. They also keep their cool when compared to internal power supplies by isolating sensitive circuits from heat and provide a safer lower output to the end product.

The WDU DC Series Wall Plug-In Transformers are completely enclosed to prevent tampering and come with a long 6-foot cord. Their equally extensive required agency approvals also help designers speed the agency approvals process for their end products. These 60 Hz, 120V devices come in a wide range of popular output voltages: 6, 7.5, 9, 12, 15, 18 and 24 Vac. Input power ranges available are from 2.3 to 38 W.

Triad’s linear technology wall plug-in power supplies are now available after the U.S Department of Energy (DOE) issued guidance to its 1975 Energy Policy & Conservation Act (EPCA). The DOE will now not consider an external power supply with specific characteristics to meet the definition of a device that is subject to EPCA regulation, as long as the power supply is not distributed for use with consumer products.

Depending on the specific model, the Triad WAU AC Series is priced from $6.23 each in minimum quantities of 100 units with delivery from stock to 14 weeks. The Triad WDU DC Series is priced depending on the specific model from $5.47 each in minimum quantities of 100 units with delivery from stock to 12 weeks. They are available off-the-shelf from Triad’s extensive distributor network.

Triad’s design engineers also can work with customers to create custom industrial and commercial power supply solutions to fit their application specific needs.
