Application
1. Model DD862 single phase electromechanical front board installed active energy meter is a kind of new style single phase two wire active energy meter, it is on the basis of original single phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad.
2. The meter completely accord with relevant technical requirements of class 2 single phase active energy meter stipulated in International standard IEC 62053-11.
3. 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 out door meter box, 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 fixed installation, the cover is made of PC material which is transparent and anti-UV molded overall, the base of the meter is made of quality steel which is after double-through antirust processing, and the terminal block 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 top-quality steel plate once molding with excellent mechanical strength, stable structure and anti-impact.
3. Voltage components and current components are used of double insulation structure, has good electrical characteristics.
4. 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.
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 configuration 5 digits display by drum wheel mechanical counter, may select 6 digits display by drum wheel mechanical counter.
7. Single component measurement single phase two wire active energy consumption, complying with standard IEC62053-11.
8. Direct connect operation, there are two types you may select. Standard configuration type B wiring, may select type A wiring.
9. Use short terminal cover, it is helpful to reduce installation space, and makes users total install conveniently.
