AVT736 A

A surprisingly simple workshop power supply with operating status signaling by means of multi-colored LEDs. The high parameters of putty were obtained thanks to the TL431 system. The PNP type switching transistor guarantees a low voltage drop allowing for more efficient use of energy supplied from the network transformer. Light-emitting diodes signal too high current consumption and output short-circuit. They approximate the currently set output voltage and the current drawn by the supplied system.
The power supply is very easy to assemble and run. It can be easily expanded by increasing the range of output voltages and the maximum output current.

The device is especially recommended for young electronic engineers who organize their own workshop, service and design studio

Selected power supply parameters:

• output voltage 2.5 - 13 V (option - 24 V)
• smooth voltage regulation
• output current - up to 0.25 A (possibility to increase)
• built-in current limiter with the possibility of changing the current value
• operation status indication - LED diodes
• power supply - 9-25 V
• printed circuit board and documentation included
  A version with a set of independent components is available
