About PSE
In this page, I will explain the electrical appliance safety law (PSE) for the AC adapter and switching power supply in an easy-to-understand manner. Based on years of experience and achievements at Unifive, we have extensive knowledge about PSE, and we can propose products that customers can relieve.
Regarding the provision of PSE
The Electrical Appliance and Material Safety Law = PSE was enforced on behalf of the Electrical Appliance and Material Control Law before April 2001 (April 2001) and is stipulated as follows.
A product (electric appliance) that is an electrical product used in ordinary households, shops, offices, etc. and specified by a Cabinet Order is a PSE mark stating that it conforms to the technical standards set by the government, a business name , Rated voltage, rated power consumption, etc., cannot be sold, and when dangerous products without these indications have circulated in the market etc., the state may order the manufacturing companies etc.Those regulated items are obliged to self-confirm compliance with technical standards. Among them, those that are particularly likely to cause danger or failure are obliged to be inspected by third party institutions as specific electrical goods.
Efforts at UNIFIVE
The AC adapter handled by our company is defined as a DC power supply device for specific electrical appliances, and we offer products conforming to the technical standards specified by PSE.
This time, from "Publication information of target of non-target relation of electrical appliance and safety law" posted on website of METI on July 25, Heisei 29 "extended code set with plug for appliance" and "extended code We will introduce and explain about "treatment of things with built-in AC adapter in the set".
Electric appliances that look similar in appearance also differ in PSE's "electric appliance name" depending on its use, and the applicable technical standards also differ. Wiring instruments that are used to connect electricity from wall outlets to electrical appliances located far away are commonly referred to as table taps or multi taps, but in PSE electrical appliance names, "extension cord set "
Products added with plugs for appliances to this multi-tap are treated as "extended cord set", but products with a USB port that can be used for charging smartphones in multi-tap are treated as "DC power supply" It becomes the same as AC adapter which we are offering.
Import manufacturers importing electrical goods from overseas are obliged to comply with the Electrical Appliance and Material Safety Act = PSE technical standards by the Electrical Appliance and Material Safety Law = PSE, so be careful.
