Application |
Model
DEM313TL single phase three wire electronic
front board installed active energy meter is
a kind of new style single phase three 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 three wire 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 |
¡ñ
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.
¡ñ
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).
¡ñ
5+1 digits display (99999.1kWh) by step
motor type impulse register
¡ñ
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.
¡ñ
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.
¡ñ
Single direction single component measure
single phase three wire active energy
consumption. It is nothing with direction of
the flow of load current. Complying with
standard IEC 62053-21.
¡ñ
Direct connect operation, type 2A wiring.
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is TK). |
