0-30V 3A Adjustable DC Supply Circuit using IC regulator UA723 and TIP3055

Robometricschool. - This is one circuit of 0-30V 3A Adjustable DC Supply Circuit using IC regulator UA723 and TIP3055 like in Figure 1 below. The main component are used in this circuit are IC regulator UA723 and TIP3055.

In here, beside we will give you circuit of 0-30V 3A Adjustable DC Supply Circuit using IC regulator UA723 and TIP3055, we also will give you component part and description. And the last we will give you link to take read more about this circuit from original source.

Component Part

  • IC regulator UA723 
  • TIP3055
  • Transformer
  • Bridge Diode
  • Capacitors
  • Resistors
Description

According Eleccircuit site describe that this is cheap adjustable 0-30V 3A Laboratory DC Power Supply circuit. It is high efficiency regulator circuit by using IC regulator UA723 and TIP3055 as power transistor so easy to install. It is designed to protect over current load maximum 3A.

AC from transformer goes through bridge rectifier diode set which compress of 4 bridge diode changing AC to DC by having C1 as a filter before sending to regulator circuit. Parallel R value (R1-R5) will be decreased to 2 ohms to detect voltage. If there is over 3A. The voltage at the base is 0.6 volts, making TR3 works. They will high voltage at the collector of TR3 and connecting with the base of TR1 making TR1 unworkable, voltage output in down respectively.

And now you can read more about circuit of 0-30V 3A Adjustable DC Supply Circuit using IC regulator UA723 and TIP3055 from original source using link here.
