The static power supply unit with separate voltage stabilization, protected against polarity reversal, overheat and short allows stable amplifier supply without capacitors.


Power Supply Unit (X1)

Power Supply Board Specifications:

·        galvanic isolation of in-/output of the power supply unit, the feedback loop, TL431 reference-voltage source stabilizer;

·        separate voltage regulation;

·        minimal interference to a vehicle electrical system;

·        Low-ESR electrolytic and film capacitors ensure high peak current and minimal interference

·        protected from polarity reversal, short-time input voltage overlapping, the power supply unit overheating and short-circuit at the output;

·        double-sided printed boards with 70 μm copper foil.
