FIELD: power supplies for radio-electronic devices.
SUBSTANCE: proposed power supply system has power supply, power buses, radio-electronic devices connected to power buses, and threshold voltage-regulator diode and resistor assembly, as well as controlled component connected to output of voltage-regulator diode and resistor assembly; it also has second threshold voltage-regulator diode and resistor assembly connected in parallel with first one and through its output, to second controlled component connected in series with first one; series-connected controlled components and threshold voltage-regulator diode and resistor assemblies are connected in parallel with radio-electronic devices under protection.
EFFECT: enhanced operating reliability of protective gear.
