Single phase prepayment meter ( prepaid meter)

Detailed Product Description

DEM091QB

SINGLE PHASE ELECTRONIC PREPAYMENT FRONT BOARD INSTALLED ACTIVE ENERGY METER

 

Application

Model DEM091QB single phase electronic prepayment front board installed active energy meter is a kind of single phase two wire active energy meter which purchase electricity by IC card, electric energy measuring, load control and using electricity management. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use for setting indoor or out door meter box. This meter has LED display shows power. It has following features: good reliability, light weight, specious nice appearance, convenient installation, etc.

Functions and features

+  Standard configuration one meter one card, can repeat input money from PC machinery

    which with IC programmer, may select one-time recharge card. (Please specified when

    ordering).

+  It has IC card with code and data against false, standard configuration use storage IC card,

    may select non-contact RF card. (Product Configuration code is QJ)

+  Standard configuration payment by kWh, may select payment by money. (Please specified

    when ordering).

+  Standard configuration of the prepayment management system use of single version, may

    select network version. (Please specified when ordering).

+  It has load control and function of automatic fault detection and instructions, standard

    configuration without function of open terminals cover and detection, may select open

    terminals cover and cut power. (Please specified when ordering).

+  Standard configuration 7 LCD digits display, 6+1 digits display (999999.1kWh), may select

    5+1LED digits display. (Product Configuration code is PB).

+  A port of pulse output passive closed (polarity), complying with standard IEC 62053-31 and

    standard DIN 43864.

+  Three LED instructions power supply state (green), signal of energy impulse (red) and

    direction of the flow of load current (yellow).

+  Automatic detection the direction of the flow of load current. When the yellow LED display,

    that is meaning the direction of the flow of load current reverse.

+  Single direction single component measure single phase two wire active energy

    consumption. It is nothing with direction of the flow of load current. Complying with standard

    IEC 62053-21.

+  Direct connect operation, there are two types wiring you may select. Standard configuration

    type 1A wiring, may select type 1B wiring (Product Configuration code is QA).

+  Front board three fixed installation, standard configuration extension terminals cover, in

    order to protect to use safety, may select short terminals cover.  (Product Configuration

    code is QD).
