Dual DC Power Supply
Variable Dual DC Power Supply Circuit
Here is a simple dual dc power supply that is easy to construct. Only by using regulator IC 7805/7905 already provides symmetrical voltage DC 5 to 25V. The DC Power Supply is built in emergency situations where the required voltage symmetry that can be adjusted to experimental electronics.
For the perfection of a dual dc power supply is still expected to suggestions from fellow practitioners of electronics to become a better power supply, for example, replace with a pair of IC regulator LM317/LM337.
Given the dual polarity power supply is built with components that are common and easily available storage reserves are included in your component. Therefore, it is easy to build and the price is cheap it is advisable to use the IC heatsink.
Dual DC Power Supply Circuit
Variable dual DC power supply is capable of providing current services to 1A per polarity. And should you use a transformer CT 2A power supply for 15V or more output currents can be well distributed. Use fuse size 500mA to prevent damage to components due to a short-circuit. Change the IC 78xx/79xx for alternate output voltage of the variable dual DC power supply.
