Single-phase plug-in power meter/three-phase plug-in power meter/public power meter manufacturer wholesale The single-chip microcomputer chip digital display relay is composed of a relay switch module and a card interface. Electronic three-phase prepaid energy meter is a new type of card-type prepaid energy meter with multiple functions such as energy metering, load control, and user information management.
Ideal product for difficult-to-adjust power grid load conditions. The connection methods of this series of electronic three-phase electric energy meters include direct connection or connection via transformer. Comply with standards. All performance indicators of this product meet all technical requirements for electronic three-phase prepaid energy meters. The work does not require adjustment of the three-phase power supply. If one line (any one of the three lines of the three-phase three-wire electric energy meter or two lines (any two of the four lines of the three-phase four-wire electric energy meter)) is powered off, the measurement accuracy will not be affected. It has phase failure. The indication function and voltage indication function have the power test signal output of one meter (household) and one card, which has good anti-counterfeiting properties. When the remaining power is equal to the alarm power, the indicator light lights up to remind the user to purchase electricity in time. When the remaining power reaches the limit, the power will be tripped and overloaded. Automatic power off, which is convenient for the power department to implement capacity expansion.
