This is the circuit diagram of adjustable symmetric 1 to 24VDC, 1A Power Supply. This power supply give dual output positive and negatif output, you can adjust both positif and negative output (+1 to +24VDC and -1 to -24VDC). This kind of power supply also known as dual polarity power supply or splitted power supply which give positive anf negatif output.

This power supply can be used for universal usage, which required not more than 1A DC current. Please take a note that you should adjust the output voltage using general multimeter or DC voltmeter before use this power supply to protect the supplied devices.

Circuit Features:

  • Low cost universal symmetric power supply
  • Just add a suitable transformer and a heatsink
  • Ideal for e.g. op-amp applications, amplifiers, …
  • Trimmers can be replaced by potmeters to allow continuous adjustment of output voltage
  • LED output indicators

Circuit Specifications:

  • Positive and negative output adjustable between 1.2 and 24VDC
  • Output current: up to 2 x 1A continuous (with suitable heatsink)
  • Max. input voltage: 2 x 24VAC
  • Very good line and load regulation
  • Low ripple
  • Short circuit protection
  • Thermal protection

The post Dual Output Stabilized Power Supply first appeared on Electronic Schematic Diagram.]]> Dual Output Stabilized Power Supply circuit diagram

This is a dual regulated and stabilized power supply, usually used to supply amplifier circuit, it also known as split powersupply. There are 3 output that are (+) voltage, (0) Ground (normal), and (-) voltage. The current output max about 0.3-0.5 A. For higher current output, power transistor is needed.

Please take a note that this circuit require center tap transformer. for example, if you need 12v output, you should connect J1 to 15v transformer output, J2 connected to 0v and J3 connected to another 15V.

The IC works ac stabilizer and regulator. There are 2 types of IC that are:

  • 78xx > for positive voltage
  • 79xx > for negative voltage

“xx” is the voltage output from IC. example, use 7809 if you need +9VDC output and 7909 for -9VDC output. For 9V output, the IC? input voltage should be at least 12V. For 12V output, the input voltage at regulator IC should be at least 15V.
