Application |
Model
DEM311TH 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.
●
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 (non polarity). 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). |
