Why Do Smart Meters Typically Have An Electrical Pulse Output Function?

The pulse output actually represents a discrete signal of electrical quantity changes. Each pulse corresponds to a certain energy unit, thus realizing the digitization and desensitization of electrical quantity measurement. 3 phase smart meter can output electrical pulses via LED flashing or the SO/KYZ terminal.

In three phase smart meter, setting the pulse output helps to separate the measurement section from the data acquisition and communication modules, allowing 3 phase wifi energy meter to maintain a modular structure. The electrical pulse output facilitates connection to a counter or data acquisition unit, enabling rapid response to electrical quantity changes.
