The power
supply, with electronic stabilisation - mainly those of laboratories - it should they are
protected from x91x92over currentx92x92 that emanates from short-circuits, erroneous
association or damage of repaired appliance. The circuit offers effective protection in
power supply with output voltage through to 45V DC. Transistor Q3 of is type in all cases
BC148, while the types of Q1-2, as well as R1-2, depend from the biggest intensity of
current, according to the table.
