Three Phase Three Wires Smart Electric Meters for AMR System with
Build In Relay
Three phase four wire electronic front board installed multifunctional active energy meter is a kind of new style three
phase four wire active energy meter. The meter completely accords with relevant
technical requirements of class 1 three phase active energy meter
stipulated in international standard IEC 62053-23 and class 2 three
phase reactive energy meter.
It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net. This
meter has LCD displays shows the active energy consumption, and there are far
infrared and RS485 communication module in it, contact with all
kind of AMR system conveniently. It has following features: good
reliability, small volume, light weight, specious nice appearance,
convenient installation, etc.
- Front board three fixed installation, the cover is made of PC
material which is transparent and anti-UV molded overall, the
bottom of the meter and the terminal is made of quality bakelite
material which is moisture-resistant, fire-retardant, high
temperature molded overall. It has following features: good
weatherability, high rigid, good insulation performance, etc.
- Have six tariffs, may select 12 daily period of times. You can set
the date arbitrary which can automatic read the meter every month.
May select single tariff function in weekend. (Please specified
- There are a clock and Maintenance-free backup lithium batteries in
it. Battery capacity detection and display all the time. It can
keep the electricity data for 12 months. The data can be kept
forever after power cut off.
- May select cycle display (default) or push the button itemized
display, it can display 14 data at most. Can select the data which
displayed. The decimal median which displayed can choose set one or
- There are a polarity port of pulse output passive closed and a
nonpolarity port of pulse output passive distant (the output rate
is 10 or 100 imp/kWh, can select ). Complying with standard IEC
62053-31 and DIN 43864.
- There are far infrared and a port of RS485 communication data. It
is use for setting and reading the meter. Set and operation have
password protection, communication agreement complying with
- Ten LED instructions respectively power supply state, signal of
energy impulse, the direction of the flow of load current, the
state rates just now and the data communications state.
- Detect active and reactive energy, active and reactive power,
voltage, current and frequency, etc. of three phase four wire
forward and reverse. Complying with standard IEC 62053-21 and IEC
- Standard configurationdirect connect operation, type 16B wiring, we
can also choose another type of wiring, and useCT (Product
Configuration code is AO) and PT & CT (Product Configuration
code is AQ) for operation.
- Standard configuration short terminals cover, may select extension
terminals cover, in order to protect to use safety. (Product
Configuration code is AM).
