| Application |
|
Model DEM082QP three phase four wire electromechanical front board installed active energy meter is a kind of new style three phase four wire active energy 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 four 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 three fixed installation, the bottom of the meter and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. The cover is also made of bakelite material and has a transparent glass window. It has following features: good weather ability, high rigid, good insulation performance, 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 double gem bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: long-life and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is QD)
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 6 digits display by drum wheel mechanical register, may select 7 digits display by drum wheel mechanical register (Product Configuration code is QV).
Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
Three components measure three phase four wire active energy consumption. Complying with standard IEC 62053-11.
Standard configuration for direct connect operation, type 16B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is QQ), type 48B wiring, and PT & CT (Product Configuration code is QR), type 48B wiring for operation.
Extension terminals cover, in order to protect to use safety.. |
