Product Brief Introduction

Model DT862 three phase electromechanical meter is fully absorb new technologies about electromechanical meter from domestic and abroad,the meter completely accord with relevant technical requirements of class 2 three phase active energy meter stipulated in international standard IEC 62053-11.It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net,it is use 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.

Function and features

-Front board two fixed installation,the cover is made of ABS engineering plastics molded overall which has a transparent glass window,the bottom of the meter is made of quality steel which is afrer 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.

-The meter frame adopt aluminum molding with excellent mechanical strength,stable structure and anti-impact.

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

-Standard configuration the meter adopt dual 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.

-All kinds of error 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 discand convenient for adjusting.

-Standard configuration 6 digits display by drum wheel mechanical counter,may select 7 digits display by drum wheel mechanical counter.

-Standard configuration without the device which can prevent retrograde,may select add the function of prevent retrograde.

-Two components measurement three phase three wire active energy consumption.Complying with standard IEC 62053-11.

-Standard confiuration for direct connect operation,type A wiring,we can also choose another type of wiring,and use CT,type B wiring.

-Standard configuration short terminals cover,may select extension terminals cover,it is for protecting use electricity safety. 

The meter is highly precise, highly sensitive. Highly reliable wide load rang, low power loss, the power in double directions. Both positive and negative work can be measured in accumulated same direction. So it can prevent any power steeling, such as reverse steeling. live-earth wire steeling, short circuit and so on.
