The voltage transducer with regulated frequency consists of power transistors, RC-timing-setting circuit and diodes, connected to transistors bases. Power transistors collectors are connected to the transformer primary winding, which consists of two base windings and an output one. The primary winding midpoint and emitter connection point of power transistors are connected to input terminals. Two resistors and the second timing -setting circuit capacitor are introduced to the transducer. The one lead of the capacitor is connected to junction point of the second transistor base and the second diode anode, the second capacitor lead is connected to base winding. One lead of each resistor is connected to cathode of the corresponding diode; the second lead of resistors is connected to common point of transformer base windings and a variable resistor. The second resistor lead is connected to positive pole of input voltage source.
