Three phase electric meter: three phase electric meter is suitable for measuring three-phase four-wire AC active energy with a rated frequency of 50Hz or 60Hz.

The digital power meter is a high-precision digital virtual instrument suitable for measuring the power of 5~400Hz three-phase sinusoidal alternating current.

Multifunctional, low-energy digital energy meters become the new favorite

The root mean square value of the sine wave voltage that the Digital Power Meter can withstand for a long time. Below this voltage, the absolute value of the measurement error of the power meter should be less than the value obtained by multiplying the relative error corresponding to the nominal acc......

Early warning reminder: When the remaining power in the Three Phase Electric Meter is less than twice the "alarm power", the "alarm indicator" will flash (with an interval of 1 second) to remind the user to purchase electricity. At this time, if the user inserts a card to respond, "alarm The flashin......

Single Phase Electric Meter gradually developed into the second generation of time-sharing electric energy meter with mechatronics structure. This kind of electric energy meter adopts 1.0-level induction system electric energy meter movement as the basis.
