DEM316AH

SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED ACTIVE ENERGY METER
 
 
Application

Model DEM316AH single phase electronic front board installed active energy meter is a kind of new style single phase two wire active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. 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, and it can display total energy consumption by step motor type impulse register. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

 
 
Functions and features
Front board three fixed installation, the cover is made of high definition transparent glass material molded overall , 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: good weather ability, high rigid, specious appearance, etc.
Standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse register. May select 6+1 digits display (Product Configuration code is SC).
Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
Standard configuration only one LED instructions signal of energy impulse (red), may select add instructions power supply state (green)and automatic detection the direction of the flow of load current and instructions by LED (when display yellow, that is meaning the direction of the flow of load current reverse). Please specified when ordering.
Single direction single component measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
Direct connect operation, there are two types wiring you may select. Standard configuration type 1B wiring, may select type 1A wiring (Product Configuration code is TH).
Extension terminals cover, in order to protect to use safety.
