Connect up to 25Vac or 35Vdc to the input using on-board jack socket or terminal block from, for example, an AC transformer or unregulated DC power supply (not included). The DC input voltage needs to be 2-3V above the required output voltage for proper operation and with a current rating sufficient for the current to be drawn which is a maximum of 1.5A.
The circuit is designed around the popular three pin LM317T voltage regulator in a TO220 package.
The kit is supplied with a heatsink, 2A bridge rectifier, smoothing capacitors, potentiometer, PCB mounted ON/OFF switch, input/output screw terminal blocks and a 2.5mm input jack socket.
This kit is not suitable for use as a DC Motor Speed Controller.
Product selection advice: Please ensure the equipment under power draws less current than the power supplies maximum rated current detailed below (do not rely on equipment rating specifications as they are often incorrect). We recommend that the power supply is rated at least 20% above the equipment to be powered so it can handle current surges, etc.
