Variable Power Supply Module, 3 - 27Vdc, 4A

3 to 27Vdc, 4 Amp maximum* adjustable stabilised power supply module supplied without mains transformer. The module accepts an AC or DC supply voltage and provides a stabilised DC output.

*The output voltage can be adjusted from 3 to 27V dc using the onboard potentiometer. However, not all input/output voltage combinations are possible and the maximum current rating falls as the input to output voltage differential increases. For example, you cannot drop a 30Vac input voltage below 18V and the maximum current rating falls to 1 Amp. Pease refer to the User Manual tables for acceptable input/output voltage ranges and maximum output currents possible.

The module is supplied fully assembled, has short circuit protection, an LED "On" indicator and screw terminal blocks for connections. All you need to do is house it in a suitable enclosure with a suitable AC or DC input, protection fuse and on/off switch. Ideal for powering many projects.

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.
