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
