POWER SUPPLIES

Each power supply of the PB-204 is regulated using a 7805 Integrated Circuit. This
circuit provides the plus and minus 15 Volt rail voltages, as well as the 5V supply
available for use in breadboard experiments. Resistors R4 and R6 are the programming
potentiometers, which are factory-set for 15V outputs. Figure 2 shows the circuit
diagram of the PB-204.
