{"product_id":"adjustable-bench-supply-3-24v","title":"Adjustable bench supply, 3 to 24 V, 3 A","description":"\u003cp\u003eMost small bench things want a voltage that is not the one your drawer of wall warts happens to contain. This is one supply with a dial instead of nine adapters with the wrong plugs.\u003c\/p\u003e\n\u003cp\u003eMains in at 100 to 240 V, adjustable DC out from 3 to 24 V, up to 3 A. US plug. Ships with a screw-terminal adapter and a barrel-jack set, so you can wire bare leads or plug a standard jack.\u003c\/p\u003e\n\u003ch3\u003eWhy current headroom matters more than volts\u003c\/h3\u003e\n\u003cp\u003ePeople buy supplies by voltage and then get bitten by current. A motor pulls far more current starting than running, and a supply at its limit sags - the voltage drops, the motor slows exactly when you need it not to, and it feels like the tool is weak. Three amps of headroom is the difference between a supply that holds its voltage under load and one that gives up.\u003c\/p\u003e\n\u003cp\u003eThat is also why this is a dial and not a switch: you can bring a new circuit up from 3 V and watch what it does, instead of connecting 12 V and finding out all at once.\u003c\/p\u003e\n\u003ch3\u003eWhere it stops\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDo not run the Mikrabench drill press above 12 volts.\u003c\/strong\u003e Its own adapter is marked 3 to 12 V and that is what the motor is rated for. This supply reaches 24, and 24 V into a 12 V motor will spin it far past its design speed and cook the windings. If you use this with the machine, set 12 and leave it. We would rather say this plainly than sell you a supply that ruins a machine we also sold you.\u003c\/p\u003e\n\u003cp\u003eIt has a dial, not a display. You set the voltage by the marking, not by reading a meter, so treat the numbers as nominal - if you need to know the actual output, measure it.\u003c\/p\u003e\n\u003cp\u003eThere is no current limit you can set. It will deliver up to 3 A into a short as happily as into a load, which is what a fuse is for.\u003c\/p\u003e\n\u003cp\u003e3 A is a bench figure, not a workshop figure. It runs small motors, LED strip, test circuits and soldering aids. It will not run anything that heats.\u003c\/p\u003e","brand":"Mikrabench","offers":[{"title":"Default Title","offer_id":47513397657791,"sku":null,"price":59.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5826\/3743\/files\/Sa3454706a3c04a2db76710248556d022f.webp?v=1789887404","url":"https:\/\/arvonelle.com\/products\/adjustable-bench-supply-3-24v","provider":"ARVONELLE","version":"1.0","type":"link"}
