Detailed Product Description
DEM313TH
SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED ACTIVE ENERGY METER
Application
Model DEM313TH 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 setting out door directly, 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 PC material which is transparent
and anti-UV molded overall, the bottom and the terminal of the meter are made of black
glass fiber which can fire-retardant and enhanced PC material, and the IP rating up to IP56. + It has following features: good weatherability, anti-impact, good insulation performance,
specious appearance, etc.
+ Standard configuration the bottom and the terminal of the meter are closed by the screw of
the meter, may select the bottom and the terminal of the meter are closed by ultrasonic.
(Please specified when ordering).
+ Standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse
register. May select 6+1 digits display (Product Configuration code is UC).
+ 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 1A wiring, may select type 1B wiring (Product Configuration code is AH).
+ Standard configuration extension terminals cover, in order to protect to use safety, may
select short terminals cover. (Product Configuration code is TG).
