Ladder dedicated single phase meter is mainly used for single-phase measurement. The meter adopts liquid crystal display and has the functions of active energy metering, modulating infrared communication, remote control of power off, automatic freezing of meter reading daily power, and real-time monitoring.

What principle does the single-phase stepped prepaid meter work according to?

The active energy measurement of the single-phase stepped prepaid meter is completed by a large-scale application-specific integrated circuit; the communication realizes reliable data communication; the data processing part adopts a low-power chip, after the MCU receives the pulse signal, the number of input pulses is accumulated and combined Realize the accurate measurement of electric energy according to the magnitude of the pulse constant; carry out data communication with the handheld computer through the infrared interface; realize the remote power-off function by controlling the relay of kilo watt-hour meter.
