Single phase electromechanical ( induction or mechanical ) energy meter

Detailed Product Description

DEM074PD( DD111)-REB meter

SINGLE PHASE ELECTROMECHANICAL FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application

Model DEM074PD single phase electromechanical front board installed active energy meter is a kind of new style single phase two wire active energy meter, it is designed on the basis of original DD284 single phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad. The meter completely accord with relevant technical requirements of class 2 single phase active energy meter stipulated in international standard IEC 62053-11. 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. The meter has novel design, rational structure, and it can display total energy consumption by drum wheel mechanical register. It has following features: compact structure design, small size, high overload, long-life, economy benefits, specious appearance, etc.

Structure and feature

+  Front board three fixed installation, the cover is made of high definition transparent glass

    material molded overall , the bottom of the meter is made of quality steel which is after

    double-through antirust processing, 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, specious appearance, etc.

+  The meter frame adopt aluminum molding with excellent mechanical strength, stable

    structure and anti-impact.

+  Voltage components and current components is used of double insulation structure, has

    good electrical characteristics.

+  Standard configuration voltage circuit and current circuit connect in the case, may select

    connect outside.

+  Standard configuration adopt magnetic thrust bottom bearing, oriented bearing is made of

    high wear resistance copper alloy bush and stainless steel needle. It has following features:

    long life and minimal friction, etc. May select double gem bearing, (Product Configuration

    code is PH).

+  All kinds of error adjustment mechanism adopt no step shifting mechanism. The meter

    starting and creeping neednt to be adjust which is finished by anti-creeping hole of disc and

    convenient for adjusting by users.

+  Standard configuration 6 digits display by drum wheel mechanical register, may select 5

    digits display by drum wheel mechanical register (Product Configuration code is PB).

+  Standard configuration without the device which can prevent retrograde, may select add the

    function of prevent retrograde. (Please specified when ordering).

+  Single component measure single phase two wire active energy consumption. Complying

    with standard IEC 62053-11.

+  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 PC).

+  Extension terminals cover, in order to protect to use safety
