If you are an electronics hobbyist, installer or technician who needs a flexible, high-power DC source without complex installation, the DROK 48V 10A 480W variable power supply is built to fit your bench, workshop or small installation needs. It’s especially useful when you require precise voltage control across a wide range, quiet thermal management, and standard protection features. Note that the unit supplies up to 10A based on load characteristics and is not a programmable constant-current source — choose it for voltage-adjustable applications and make sure connected devices draw below the 10A maximum.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this supply run at any voltage between 0 and 48V?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, you can set output anywhere from 0 to 48V in 0.1V steps using the built-in potentiometer.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What is the maximum current this unit can provide?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The maximum available output current is 10A; the actual current depends on your connected load.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"DROK","offers":[{"title":"Default Title","offer_id":48413457055901,"sku":"B08GFQZFC1","price":56.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/drok-front-panel-display.jpg?v=1781267026","url":"https:\/\/nexoltic.com\/products\/drok-48v-10a-variable-ac-to-dc-power-supply-480w","provider":"Nexoltic","version":"1.0","type":"link"}
