The kit comes "complete", which means the transformer, power cord and fuse holder are included. Most power supply kits leave finding such things to the builder.
Output is via screw terminals, making this a good bench supply for the kit builder. Voltage may be varied up to about 24 volts DC and is well regulated; i.e. the voltage is very stable.
Using the LM317T I.C. and the included 24 volt, 1 amp transformer permits an output range from about a volt to 21 volts. Higher current is available at the higher voltages but lower voltage are at lower currents; for example, around 5 volts the maximum output is around 350 mA. Maximum current is available in the 18 to 22 volt range .
Ripple (on line noise) is finite, making this a good kit for those audio and R.F. projects where you do not care to hear power line noise.
Note: We do not recommend a beginner build this kit unless he or she has some experienced supervision to help. Any kit that connects to the A.C. power line is potentially dangerous to the inexperienced builder.
