DEM082WA

THREE PHASE FOUR WIRE ELECTROMECHANICAL FRONT BOARD INSTALLED ACTIVE ENERGY METER
 
 
Application

Model DEM082WA three phase three wire electromechanical front board installed active energy watt-hour meter is a kind of new style three phase four wire active energy watt-hour meter, it is on the basis of original D86 three 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 three phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase three wire AC electricity net, it is use for setting indoor or out door meter box.

 
 
Functions and features
Front board three 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 weather ability, 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 WM)
All kinds of error 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 WG).
Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
Two components measure three phase three wire active energy consumption. Complying with standard IEC 62053-11.
Standard configuration for direct connect operation, type 13A wiring, we can also choose another type of wiring, and use CT (Product Configuration code is WB), type 5A wiring, and PT & CT (Product Configuration code is WC), type5A wiring for operation.
Extension terminals cover, in order to protect to use safety.
