| LM723 2.5A 0-30 Volts Variable Power Supply |
This is a very high quality power-supply with a continuously variable stabilized output that is adjustable between 0 and 30VDC. the heart of the power supply is LM 723 which drives the BD137 and then the 2N3055. The circuit has great stability at voltage changes and provides short circuit protection.. Drive the circuit with 24 Volts 3A from a transformer. the 2N3055 needs a good heat sink. see the circuits given above.
