Meba-tested meters-MB071VB 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, and development long-life technology. 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 accurate 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 register. It has following features: high overload, power loss, long-life, specious appearance, etc.

1. 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 weatherability, 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 is used of all closed vacuum pouring coil by epoxy resin. Current components is 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 adjust 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 register, may select 6 digits display by drum wheel mechanical register (Product Configuration code is VE).
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 wiring you may select. Standard configuration type 1A wiring, may select type 1B wiring (Product Configuration code is VA).
9. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is RB).
