        Single phase

        EN-22S is a direct connection type of single phase AMI meter on the modular design, which is
        used to measure electric energy accurately for commercial and residential customers according to the international standards of energy meter. The meter supports varieties communication mediums for remote management with hot swappable communication module such as WIFI/RF/GPRS/3G/4G/NB-IoT/Wi-SUN/PLC modules etc. Meter can supports multi-protocols, such as DLMS, IEC62056-21, DL645-2007, Modbus-RTU,etc.
        EN-22S has plentiful anti-tamper features and irregularities events detection function, like load
        earth, neutral missing, current reversal, neutral disturbance, magnetic tamper, 35kV ESD
        disturbance, cover open. Meter accuracy will immune or record the events for punitive measurement under these irregularities events. Pushing to ensure utility asset protection and revenue growth.
        It can be utilized for prepayment and post payment applications which is select-able by utility with CIU or remote communication
        EN-22S energy meter is an all-electronic, solid state polyphase energy meter which accurately
        Measures all parameters of the supply voltage,current,power factor etc.,in addition to active,
        Reactive and apparent energy(As the case may be).EN-22S is designed around an Application Specific Integrated Circuit(ASIC) based micro-controller with its own programming language.It also has a high degree of programmability to accommodate various types of applications and tariffs.

        Technical Features

        1.Energy Registers
        The Meter is capable of measuring Active,Reactive,and Apparent energy, as well as the harmonic energy and fundamental energy.
        2.Maximum demand and MD Integration Period
        The meter is programmed for Maximum Demand(MD) integration period of 15/30/60
        minutes(default is 30 minutes).The demand is monitored during each demand interval set with
        15/30/60 Minutes integration and the maximum of these demands is stored as Maximum Demand.
        Whenever the Maximum Demand is reset, the maximum demand values or egistered shall be stored along with date and time. The Universal (0–24Hours) Maximum Demand: A separate register shall be present to record the maximum demand for 24 hours, since last reset known as universal demand register.Meter will compute and register active MD.
        3.Maximum demand reset
        Maximum Demand can be reset by one of the following mechanisms. The supplied meter has one or more of the following options given below:
        a.Through Meter Reading Instrument in the form of an authenticated command.
        b.Automatic ally at 1st of every month at the time of Billing.
        c.Remote command via PLC communication from data server.
        d.MD reset through push button can be enable or disable before production.
        4. Maximum demand reset counter
        Whenever the maximum demand is reset,this counter is incremented by one and MD reset counter is maintained by meter to keep track of MD reset operations.
        5.Cumulative demand register
        Cumulative demand(CMD) is the sum of all the 0-24hrs maximum demands which have been reset so far.This register along with MD reset counter helps in detecting an yun authorised MD Reset performed.
        6.Tariff and Time of Use
        Meter supports four tariff and Time of Use function.The tariff and time zone can be set from the local communication portor the remote communication module
        7.Daily freeze data
        Daily freeze function supports to freeze the every day’s energy data according to the configure date number,It can help utility to analysis the latest daily energy data.
        8.The Load Survey
        Load survey profiling is optional for eight parameters on15/30/60 minutes interation period(default is 30minutes) for default 60days. The two parameters configured for load survey recording a reactive forwarded and apparent demand. The data volume can be extended to 366days for all Instantaneous parameters and billing parameters.
        The data can be read by CMR Ior remote communication method.This can be vieweding raphical for mand this data can also be converted to a spread sheet through the BCS or data server.
        9.Data Communication
        The meter has a infra-red coupled isolated serial communication interface and one optional wire port RS485/RS232/M-BUS for local data reading and replaceable module for remote management,which can be WIFI/RF/GPRS/3G/4G/NB-IoT/Wi-SUN/PLC module.
        10.Tamper & irregularities detection & logging
        The special software in consumer energy meter is capable of detecting & reporting conditions of tampers and fraud like current polarity reversal,magnetic tamper,etc along with date and time.The following tampers can be supported:
        11.Load control by internal magnetic latch relay: When meter has the internal
        Magnetic latch relay,it can control the load connection/disconnection by the local logic defination or remote communication command.
        12.Calibration LED
        Meter can output calibration LED pulse for active,reactive,and apparent.The default accuracy LED pusle is for active and reactive energy.
        If meter has requirements for RJ45 port,meter can output accuracy pulse via RJ45.
