This is simple and Low-cost Electronic Circuit Project of Multiple Output DC Converter Circuit Diagram . A DC converter circuit taking one single DC input and converting to parallel multiple DC outputs. Simple But Multiple Output DC Converter Circuit Diagram: Circuit Project Notes : This circuit uses a single DC input (nominally 12 Volt) and converts to four simultaneous output voltages of 9, 6, 5 and 1.5 Volts. The output voltages are controlled by common 78xx series regulators, offering 9, 6 and 5 Volt DC outputs. The 1.5 Volt supply is derived using an LM317 regulator. To reduce power and heat the LM317 is fed from the 5 Volt regulator output. The LM317 output is calculated from: Vo = 1.25 (1 + R1/R2) With R1 200 ohms (use 180 plus 22 ohm in series) this works out to be 1.5 Volt. F2,3,4,5 are the output fuses and are set at 500 mA (0.5 A). If the full 500mA is taken from each output then the DC input supply must be capable of sourcing at least 2 Amp. LED 1 illuminates to show the ci...

Multiple Pedals or Effects in the same box - switching.

Multiple Switching Operation is a system where the street light can be energized and de-energized (switch ON and OFF) from multiple location by simply a push button switch. Figure below (A)  illustrate the layout of the street lights (L1,L2,L3…Ln) which are installed in the street of camp M. By pressing any one of the push button switches P1,P2,P3,P4, and P5 installed in buildings A,B,C,D, and E respectively, one can switch On and OFF the street lights. Multiple Switching Operation applied to lights in a camp Control Circuit Operation Figure below (B) illustrates the control circuit of a multiple switching operation. Encircled A and B maybe the power made of relay or contactors. Encircled C is the power contactor that will energized the street lights (L1,L2,L3…Ln) directly from the source. Pressing any one of the five push button switches (P1,P2,P3,P4 and P5) will energized contactor A. For example, pressing the push button switch P3 which is at the Administrator building will cause th...
