Universal stabilised power supply with 5 fixed voltage DC outputs. The circuit uses an LM317T with heatsink to provide 1.5A of continuous output power and has a large 4700uF smoothing capacitor for good stabilisation.
Depending on the transformer used for the input, it gives the related DC output at a power rating of up to 1.5A. It can be used as power supply for many electronic devices such as radios, tape recorders, portable TV's, etc.
Kit includes all board mounted components including large heatsink and solder for assembly. You need to add a 12Vac/1.5A transformer.Specifications
