Power supply arrangement comprising a direct voltage monitoring circuit. A power supply arrangement comprising a direct voltage monitoring circuit for at least two different-polarity direct voltages connected to a common reference potential, and including a signal transmission element. The monitoring circuit arrangement has an enhanced accuracy of response with limited circuitry and cost. A series connection of a zener diode and a resistor is connected in shunt with each direct voltage. The junction point of each zener diode and resistor is connected to the base of a transistor. A first electrode of each transistor is connected to the signal transmission element and a second electrode.
