DEM191QJ

SINGLE PHASE ELECTROMECHANICAL ANTI-STEAL FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application

Model DEM191QJ single phase electromechanical front board installed active energy meter is a kind of new style single phase two wire active energy meter which has several properties of anti-steal, it is on the basis of original DEM073 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.

Functions and features

It has a group of supplementary coil more than ordinary electromechanical meter to be complicated with its measuring circuits.
It can resist stealing power supply as following: to earth, reverse connection, separate current, from condenser.
Its function and connection circuits are the same as ordinary meter under the correct operating.
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, specious appearance, etc.
Standard configuration bottom bearing is used of double gem bearing, 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 (Product Configuration code is QD) or magnetic suspension (Product Configuration code is QP).
Its register is indirection and use the transmission ratio between positive and negative, Standard configuration 6 digits display by drum wheel mechanical register, may select 5 digits display by drum wheel mechanical register (Product Configuration code is QG).
Standard configuration without handle, may select add a handle for carrying the meter conveniently. (Please specified when ordering).
Single component measure single phase two wire active energy consumption. Complying with standard IEC 62053-11.
Direct connect operation, there are two types you may select. Standard configuration type 1B wiring, may select type 1A wiring (Product Configuration code is QK).
Extension terminals cover, in order to protect to use safety.
