Application:

        Model DD5558 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 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 accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is used 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: High overload, power loss, long-life, specious appearance, etc.

Functions and features:

1- Front board three holes fixed installation, the base of the meter and the terminal block 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.

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

3- Voltage components and current components is used of double insulation structure, has good electrical characteristics.

4- Standard configuration bottom bearing is used of dual jewel bearing, upper 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 magnetic thrust bearing or magnetic suspension

5- All kinds of adjustment mechanism adopt no step shifting 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 con figuration 6 digits display by drum wheel mechanical counter, may select 5 digits display by drum wheel mechanical counter

7- Standard configuration without anti-reverse device may select add anti-reverse function.

8- Standard configuration without handle, may select add a handle for carrying the meter conveniently.

9- Single component measure single phase two wire active energy consumption. Complying with standard
