Ability Level 2 : Moderate

This kit is a quick, neat and inexpensive way to provide a regulated, dual polarity DC power supply to a project in the range +/- 5 to 18Vdc/1A.

The kit provides a universal PCB for mounting any pair of 78xx (positive) and 79xx (negative) series 3 terminal regulators. The regulators must be used in positive and negative pairs but they do not have to have matching voltages (e.g. you can use a +5V and a -12V regulator together). Each regulator can provide up to 1A load current and features on-chip protection circuitry that simple shuts the chip down in the event of over heating or excessive current.

The kit comes with heatsinks, 4A bridge rectifier, smoothing capacitors, 2 x LED power indicators and input/output terminal blocks. The input voltage needs to be 3V above the required output voltage for proper operation.

The user supplies any pair of 78xx and 79xx series regulators from 5 to 18V (i.e. 7805 & 7905, 7808 & 7908, 7812 & 7912, 7815 & 7915, 7818 &7918) and a centre tapped transformer with a power output rated at 7VA minimum.
