The invention belongs to the technical field of power equipment, and in particular relates to a power meter demand interval measurement pulse output converter. According to the power meter demand interval measurement pulse output converter, a pulse input interface P1 high end is connected with a self-recovery fuse F1; a pulse input interface P1 low end is connected with a pulse converter power supply low end GND; the other end of the self-recovery fuse F1 is connected with a load resistor R1, a voltage-regulator diode D1 cathode and a resistor R2; the other end of the resistor R2 is connected with a pin 1 of a not-gate integrated circuit U1A; a pin 2 of the not-gate integrated circuit U1A is connected with a pulse input interface P2 high end; a pulse input interface P2 low end is connected with the pulse converter power supply low end GND; and a pulse output converter power supply high end VCC is connected with a power supply battery BT1 high end of a power supply switch S1. The power meter demand interval measurement pulse output converter has the characteristics of being simple in structure, easy to operate and safe and reliable to use, and demand interval errors can be measured by using a universal counter.
