Application:

       DD283/DD284 single phase electromechanical meter, and fully absorb new technologies about electromechanical meter fro m 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 accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use for setting indoor or outdoor meter box. The meter has novel design, rational structure, and it can display total energy consumption by drum wheel mechanical counter. It has following features: Compact structure design, small size, high overload, long-life, economy benefits, specious appearance, etc.

Functions and features:

1- Front board three holes fixed installation, the cover is made of high definition transparent glass material molded overall, the base of the meter is made of quality steel which is after double-through antirust processing, and the terminal block is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: good weather ability, high rigid, specious appearance, etc.

2- The meter frame adopt aluminum alloy molding with excellent mechanical strength, stable structure and anti-impact.

3- Voltage components and current components are used of double insulation structure, have good electrical characteristics. Standard configuration voltage circuit and current circuits connection meter ca se, may select connection outside.

4- Standard configuration adopt magnetic thrust bottom bearing, upperoriented 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 dual gem bearing.

5- All kinds of error adjustment mechanisms have fine adjustment mechanism. The meter starting and creeping needn't to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by users.

6- Standard configuration 6 digits display by drum wheel mechanical counter, may select 5 digits display by drum wheel mechanical counter.

7- Single component measure single phase two wire active energy consumption. Complying with standard IEC 62053-11.

8- Direct connect operation, there are two types you may select. Standard configuration type B wiring, may select type A wiring

9- Extension terminal cover, it is for protecting use electricity safety.
