2. Intellectual property
The content of this website — text, diagrams, photographs, layout and source code — is the property of ATECELECTRIC Co., Ltd. unless stated otherwise. It may be read, printed and quoted for the purpose of evaluating our products, including in your own internal documentation. It may not be republished, sold, or used in marketing material by another party without written permission.
The winding architecture of the PECO Harmonic Energy Recycling Transformer is protected by Korean Patent No. 10-2546570.
PECO and PECO Powersaver are product names of ATECELECTRIC Co., Ltd. Other names and marks appearing on this site belong to their respective owners and are used only to identify the equipment concerned.
3. Accuracy of the information here
The technical information on this site describes our standard product range and is prepared with care. It is intended to help you decide whether to begin a technical review — it is not a specification for a particular installation.
Dimensions, weights and efficiency figures are indicative. The transformers are wound by hand and the design varies with rated voltage, so values differ between production lots. Figures for the specific unit supplied are stated in the product manual delivered with it.
Suitability for any given facility is confirmed only after review of the single-line diagram, transformer rating, voltage range and load composition. Nothing on this site constitutes a guarantee of energy savings; we publish no saving percentage, and results are measured on site under an agreed protocol.
4. Certification and conformity
The Attestation of Conformity issued by TÜV SÜD Product Service GmbH (No. N8A 103329 0002 Rev. 00) was obtained voluntarily under the Low Voltage Directive 2014/35/EU. Under that directive a manufacturer may declare conformity itself; the attestation confirms third-party assessment, and the CE marking is affixed under the manufacturer’s own responsibility.
Certification scope varies by model, rating and destination market, and applicable certificates are confirmed at project stage.
5. Installation and safety
PECO Powersaver is connected in series with a low-voltage distribution system and must be installed by qualified electrical personnel, in accordance with the product manual and the wiring regulations applicable at the site. Installation requires a planned outage of the main distribution.
ATECELECTRIC accepts no liability for damage or injury arising from installation, modification or operation carried out contrary to the product documentation.
6. External links
Where this site links to an external page, we have no control over its content and accept no responsibility for it.
7. Governing law
Unless otherwise agreed in a contract, the laws of the Republic of Korea govern the content of this website. This does not affect any mandatory consumer protection rights available to you under the law of your country of residence.
