1 Triad Announces Linear Wall Plug-In Power Supplies For Industrial and Commercial Applications Low To Zero Noise Designs for Superior Performance, Reliability and Life Perris, CA March 16, 2018 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, 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. -More- Triad Linear Design Wall Plug-In Power Supplies Page 2 of 2

2 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 a guidance (attached) 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 and are clearly labeled as such. 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 deliver 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. (end) Triad Magnetics Triad Magnetics is a global leader in the design and manufacture of transformers, power supplies and inductors for a wide range of applications, including switch mode/high frequency, wall plugin, power transformers, inductors and audio transformers.

4 This final document represents the definitive view of the agency on the questions addressed and may be relied upon by the regulated industry and members of the public. This and other guidance documents are accessible on the U.S. Department of Energy, Energy Efficiency & Renewable Energy web site at: Guidance Type: Definitions and Scope of Coverage Category: Consumer Products Product: External Power Supplies Guidance Version: FINAL Issued: December 20, 2017 Effective Date: December 30, 2017 Q: Are power supplies that are packaged with or used to operate commercial or industrial end-use devices covered by the Department of Energy s energy conservation standards? A: The Energy Policy and Conservation Act of 1975, as amended ( EPCA ), 1 defines an external power supply 2 as an external power supply circuit that is used to convert household electric current into DC current or lower voltage AC current to operate a consumer product. 42 U.S.C. 6291(36); see also 10 CFR EPCA defines a consumer product 3 as any article... of a type which in operation consumes or is designed to consume energy... and which, to any significant extent, is distributed in commerce for personal use or consumption by individuals; without regard to whether such article of such type is in fact distributed in commerce for personal use or consumption by an individual U.S.C. 6291(1). DOE will not consider a power supply with any one of the following characteristics to meet the definition of an external power supply under EPCA, so long as the power supply is not, in fact, distributed in commerce 4 for use with a consumer product: 1. a power supply requiring 3-phase input power, which is incapable of operating on household current; 2. a DC-DC only power supply, which is incapable of operating on household current; 3. a power supply with a fixed, non-removable connection to an end-use device that is not a consumer product 5 ; 1 42 U.S.C The terms external power supply or EPS as used in this guidance document are each limited to the definition of external power supply under EPCA. See 42 U.S.C. 6291(36). 3 The term consumer product as used in this guidance document is limited to the definition of consumer product under EPCA. See 42 U.S.C. 6291(1). 4 The terms to distribute in commerce and distribution in commerce mean to sell in commerce, to import, to introduce or deliver for introduction into commerce, or to hold for sale or distribution after introduction into commerce. 42 U.S.C. 6291(16). 5 For purposes of this guidance, the phrases not a consumer product and non-consumer product refer to those devices that do not fall within the definition of consumer product under EPCA. See 42 U.S.C. 6291(1). 1

5 4. a power supply whose output connector is uniquely shaped to fit only an end-use device that is not a consumer product; 5. a power supply that cannot be readily connected to an end-use device that is a consumer product without significant modification or customization of the power supply itself or the end-use device; 6. a power supply packaged with an end-use device that is not a consumer product, as evidenced by either: a. such device being certified as, or declared to be in conformance with, a specific standard 6 applicable only to non-consumer products; or b. such device being excluded or exempted from inclusion within, or conformance with, a law, regulation, or broadly-accepted industry standard where such exclusion or exemption applies only to non-consumer products; or 7. a power supply distributed in commerce for use with an end-use device where: a. the end-use device is not a consumer product, as evidenced by either the circumstances in (6)(a) or (6)(b) above; and b. the end-use device for which the power supply is distributed in commerce is reasonably disclosed to the public, such as by identification of the end-use device on the packaging for the power supply, documentation physically present with the power supply, or on the manufacturer s or private labeler s public website; or 8. a power supply that is not marketed for residential or consumer use, and that is clearly marked (or, alternatively, the packaging of the individual power supply, the shipping container of multiple such power supplies, or associated documentation physically present with the power supply when distributed in commerce is clearly marked) FOR USE WITH COMMERCIAL OR INDUSTRIAL EQUIPMENT ONLY or NOT FOR RESIDENTIAL OR CONSUMER USE, 7 with the marking designed and applied so that the marking will be visible and legible during customary conditions for the item on which the marking is placed. A power supply that does not meet one or more of the eight criteria in the preceding paragraph may still fall outside of the definition of external power supply under EPCA. This guidance provides eight specific examples of circumstances where DOE will not consider a power supply to meet the definition of external power supply under EPCA. However, nothing in this guidance precludes a person from asserting that a specific power supply that does not meet one or more of these eight criteria nonetheless does not meet the definition of external power supply under EPCA. 6 For example (and without limitation), a power supply model intended for use with an end-use device that is certified to the following standards would not meet the EPCA definition of an EPS: (1) CISPR 11 (Class A Equipment), Industrial, scientific and medical equipment Radio-frequency disturbance Limits and methods of measurement ; (2) UL 1480A, Standard for Speakers for Commercial and Professional Use ; (3) UL 813, Standard for Commercial Audio Equipment ; and (4) UL 1727, Standard for Commercial Electric Personal Grooming Appliances. 7 Non-material deviations from such marking cited in (8) will not preclude satisfaction of the circumstances set forth in this paragraph (8). In addition, DOE may in its discretion determine that a power supply satisfies the circumstances set forth in (8) (provided all other conditions are satisfied) where such marking consists of language other than that specified in (8) but that nonetheless clearly conveys that the power supply is not marketed or intended for use with consumer products. 2

6 While a power supply that meets the definition of an external power supply under EPCA 8 would be considered a covered product, 9 DOE has established energy conservation standards only for certain categories of external power supplies. DOE notes that this guidance document, which is not a significant regulatory action under Executive Order 12866, serves solely to clarify DOE s views regarding the existing external power supply definition. Currently, external power supplies that meet the definition of a Class A external power supply are required to meet specific energy conservation standards articulated at 10 CFR (w)(1)(i). Additionally, direct operation external power supplies are also required to meet energy conservation standards articulated at 10 CFR (w)(1)(ii). Lastly, an external power supply shall not be subject to the standards in paragraph (w)(1) of 10 CFR if it is a device that requires Federal Food and Drug Administration listing and approval as a medical device in accordance with section 513 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360(c)). More information on the current external power supply energy conservation standards is available on the DOE s External Power Supply website. 8 See 42 U.S.C. 6291(36) U.S.C. 6291(2). 3
