Main functions
● High performance 32 bit ARM9 kernel CPU with the embedded linux operation system.
● Each concentrator can administer no less than 1000pcs single phase energy meters and 200pcs three phase energy meters.
● Uplink communication adopts the public network mode which is compatible with GPRS/CDMA, Ethernet, etc.
● Downlink communication can choose 485, carrier wave (broadband or narrowband) or micro-power wireless, etc..
● Software upgrading based on the local mode or the remote online mode is available.
● Anti-tamper detection.
It has the characteristics of high precision, small size and convenient installation.
Single-phase and three-phase four-wire meters use the same modular design.
It can simultaneously measure grid voltage, current, power, frequency, electrical energy and other parameters.
working principle
The electric energy meter obtains the voltage sampling signal from the voltage divider, and the current sampling signal from the current divider.
The voltage and current product signal is obtained through the multiplier, and then a counting pulse whose frequency is proportional to the
product of voltage and current is generated by frequency conversion.
