LM3914 LED driver with integrated LEDs are able to follow the volume amp circuit I’ve used a few of these and many similar to the output of the integrated circuit by adding additional control elements able to control high power loads
CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles
Circuit 47k potentiometer with a high low audio signal by the lamps burning range can adjust the L1 coil supply voltage for the filter not use happens on but I suggest to use has many benefits known to our network situation in the grave lamp instead 230v ac working with different loads can connect the application lamp cabin plexiglass with a little expensive materials prepared
CAUTION The circuit is working with high voltage. Be careful with the capacitor connections. If you connect the + – poles reversely, there may be big explosions at high voltage.

LM338K 5 amp Regulated Power Supply Circuit
National Semiconductor integrated regulator often uses LM3XX Series, and I saw a lot of sound systems used in the device power supply of the charging circuit etc in various systems. LM338K 1.2 with very little passive elements .. 5 amp power supply can be 32 volts.
A very simple circuit but stylish design a PCB can be useful Integrated given by the powers of 5 amps, but under certain conditions at high powers are going to use it first integrated the “K” series Metal large sheath which to use and good cooling suggest you do Setting the application can be made 1.2v.. 25v volts to 32 volts cancel the R2 resistance value of R3 potentiometer 5k 2.5k Use
LM3914 220V Licht-Vu-Meter-Stromkreis
Der LM3914-LED-Treiber mit integrierten LEDs kann dem Lautstärkeverstärkerkreis folgen, von dem ich einige verwendet habe, und viele, die dem Ausgang des integrierten Schaltkreises ähnlich sind, indem zusätzliche Steuerelemente hinzugefügt werden, die hohe Leistungslasten steuern können
VORSICHT Seien Sie vorsichtig beim Arbeiten mit Hochspannungskondensator-Schaltkreisanschlüssen. Vorsicht + – Wenn Sie die Hochspannungspolarität anschließen, kann es zu starken Explosionen kommen, bevor Sie den versicherten Stromkreis der Stromleitung betreiben. Tragen Sie eine Schutzbrille
