Normally you have a switching power supply that plugs into the wall and provides something like 5V or 9V or 12V regulated DC. This \u003cstrong\u003esplit\u003c\/strong\u003e power supply is interesting in that it gives you \u003cstrong\u003etwo power supplies! \u003c\/strong\u003eOne is a positive-with-respect-to-ground +12VDC. The other is negative-with-respect-to-ground -12VDC. The max voltage differential is 24V from negative to positive so you are getting a true 'split supply'\u003c\/p\u003e\u003cp\u003eExcellent for use with analog electronics, motor controllers, lab equiptment, modular synthesizers, or anything else where you've found yourself puzzling over the need for a matching negative power supply.\u003c\/p\u003e\u003cp\u003eThe black wire is your every day classic +12VDC with center positive. The white wire is the negative supply, its \u003cem\u003ealso\u003c\/em\u003e center positive which means the center is the same as the black wire's ground. The 'ring' of the white-cable connector is -12VDC. You can draw about 500mA from each side, a total of 1A. Please note that the output is not as strictly regulated as some other power adapters you may have used, the floating voltage can be +-13V and at max draw, droop down to +-11V or so. You may want to have an extra linear regulator if you want the output to stay rock-solid over a wide current-draw range.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eCable lengths: 1.2m each\u003c\/li\u003e\n\u003cli\u003e5.5mm \/ 2.1mm DC jack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 86.0mm x 48.0mm x 31.0mm \/ 3.4\" x 1.9\" x 1.2\" \u003c\/p\u003e\n\u003cp\u003eProduct Weight: 127.0g \/ 4.5oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":53774835319149,"sku":"tff1787257429867","price":11.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0526\/9869\/files\/switching-split-power-supply-12v-500ma-split-supply-discontinued_1.jpg?v=1787257434","url":"https:\/\/www.ruralgoods.shop\/products\/switching-split-power-supply-12v-500ma-split-supply-discontinued","provider":"My Store","version":"1.0","type":"link"}
