APPLICATION

EM131TP THREE PHASE FOUR WIRE IMPULSE ELECTROMECHANICAL FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM131TP three phase four wire electromechanical front board installed active energy meter is a kind of three phase four wire active energy meter which is designed and manufactured by our company and developed for adapting townsman using electricity  measuring and concentrative management as multiplayer residence and storied buildings and supplying collecting transcription meter system impulse group of formed direct ratio with using electricity quantity. The meter completely accord with relevant technical requirements of class 2 single phase active energy meter stipulated in international standard IEC 62053-11 and standard IEC 62053-31. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net, it is use for setting indoor or out door meter box.

Functions and features
● The meter use type EM082 three phase meter as basal meter, and add an impulse occurring device sampling by magnetoelectricity sensor. It has the following function: adjust impulse width, LED impulse output indication, anti-dithering, wide temperature working range (-40-80℃) high reliability and long life, can choose inner placed current as power supply electrical source.
● Front board two fixed installation, the cover is made ABS engineering plastics molded overall has a transparent glass window, the bottom of the meter is made of quality steel which is after double-through antirust processing, and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: Economy benefits, specious appearance, etc.
● Standard configuration the meter adopt double gem bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: long-life and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is TD)
● Standard configuration 6 digits display by drum wheel mechanical register, may select 7 digits display by drum wheel mechanical register (Product Configuration code is TV).
● Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
● Standard configuration one port of pulse output active (polarity), May select increase a distant port of pulse output passive (nonpolarity), contact with all kind of AMR system conveniently, complying with standard IEC 62053-31. LED instructions signal of energy impulse (red).
● Three components measure three phase four wire active energy consumption. Complying with standard IEC 62053-11.
● Standard configuration for direct connect operation, type 16B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is TQ), type 48B wiring, and PT & CT (Product Configuration code is TR), type 48B wiring for operation.
● Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is UP).
