The proposed electric power meter for direct-current consumers contains a scaling current transducer, a multiplier, a voltage-to-frequency converter, a display unit, a scaling voltage transducer, and a frequency divider. The output of the current transducer is connected to the first input of the multiplier. The output of the multiplier is connected to the input of the voltage-to-frequency converter. The output of the voltage transducer is connected to the second input of the multiplier. The input of the frequency divider is connected to the output of the voltage-to-frequency converter, and the output is connected to the input of the display unit.
