Regulated power supply 12 volt

Description of Service

This circuit is simpler and better nutrition services organization for the continuing effort .. Forthis
It is very common ..
In addition to the simplicity of installation .. Is also composed of elements are cheap andavailable



Standardization Department

Source of nutrition 220 volts or 110
According to the converter output voltage: 12 volts continuous effort
Nizttiar Output: 1 amp

Integrated circuit containing
Internal protection against minors Short Circuit



Circuit diagram



Explain the circuit

At first the switch
Effort to reduce power source whether it is 110 volts or 220 volts AC to a small effort
6-volt ..
Then comes the bridge of unification, which converts the AC voltage wave to a continuous effort
Ripple in the output .. And that the reception of intensive Ptenaim this effort to reach as much as
Possible to stability .. Then comes the role of the integrated circuit that contains within it
On a set of transistors that organize the ongoing effort to give unregulated in
Continuously output a constant voltage regulator



Installation Service

The heart of this circuit is the circuit
Integrated .. To this must be emphasized and developed the right way and taking into account the direction
