摘要

ELECTRONIC COLOR COMPARATOR, essentially characterized by the fact that the power supply is made up of a transformer that sends the current to a uniform lighting lamp, having previously rectified, stabilized and filtered the current using two silicon diodes (D5 and D6), a Zener diode (DZ2) and an electrolytic capacitor (C2), having provided that at the output of the secondary of the transformer, a bridge rectifier circuit is provided, consisting of the diodes (D1, D2, D3 and D4), being arranged in series with the positive pole of the rectifier output a wound resistance (R3), stabilizing the voltage by means of a Zener diode (DZ1) and filtering by the capacitor (C1).
