WORKSHOP SUPPLY - PRINTED PLATE

Producer: AVT

The adjustable workshop power supply - apart from the soldering iron, multimeter, oscilloscope and generator - the basic equipment of the electronics workshop. Even a beginner electronics must be equipped with at least a power supply, a soldering iron and a multimeter. That is why many of them construct their first power supplies themselves before they "mature" to buy a factory product. I decided to deal with the power supply design, but using modern components for this purpose. I also equipped him with features that I found necessary.
Recommendations: a full-fledged, modern, functional power supply with regulated voltage, output current and protection current, which is useful in many electronic workshops.

Basic information:

• output voltage range 0.6 ... 24 V.
• output voltage is set roughly, with a step of 1V and exactly with a step of 0.1 V.
• software function for limiting the maximum output voltage - overvoltage protection.
• maximum 3 A output current
• programmable current limitation in the range of 0.1 ... 3 A.
• current limit set roughly in step 1 A and exactly in 0.1 A. steps
• function of programmed overcurrent protection in the range 0.1 ... 3 A set with 0.1A resolution.
• digital measurement of output voltage (resolution 0.1V) and output current (resolution 0.01 A).
• the function of limiting the loss power on the control transistor by automatically switching the transformer tap to half of the secondary alternating voltage at the output voltage below +12 V (with 0.2 V hysteresis).
• possibility of work without a microprocessor controller - control by means of potentiometers (without voltage and output current measurement).
