DEM073WC

SINGLE PHASE ELECTROMECHANICAL FRONT BOARD INSTALLED ACTIVE ENERGY METER
 
 
Application

Model DEM073WC single phase three wire electromechanical front board installed active energy meter is a kind of new style single phase three wire active energy meter, it is designed on the basis of original DD862 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 three wire 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: high overload, power loss, long-life, specious appearance, etc.

 
 
Functions and features
Front board two fixed installation, the cover is made of PC material which is transparent and anti-UV molded overall, the bottom of the meter is made of black glass fiber which can fire-retardant and enhanced PC material, 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, anti-impact, 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 the meter adopt magnetic thrust bottom bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: Small abrasion, long life and minimal friction, etc. May select double gem bearing (Product Configuration code is WI)
All kinds of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn’t to be adjust which is finished by anti-creeping hole of disc and convenient for adjusting by users.
Standard configuration 5 digits display by drum wheel mechanical register, may select 6 digits display by drum wheel mechanical register (Product Configuration code is WF).
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, type 2A wiring.
Extension terminals cover, in order to protect to use safety.
