Active Energy
Meter |
|
|
Application |
|
Model
DEM081PD three phase four wire electromechanical front board
installed active energy meter is a kind of new
style three phase
four wire active energy meter, it is on the basis of original three
phase electromechanical meter, and
fully absorb new
technologies about electromechanical meter from domestic and abroad, and
development long-life
technology . 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 out door meter box, 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 three holes fixed installation, ap and down mounting holes
center distance is
209 mm or 225mm, users can choose
any one by themselves.
--The
cover is made of PC material which is transparent and anti-UV molded
overall, the
base of the meter and the terminal
block is made of quality bakelite material which is
moisture-resistant, fire-retardant, high temperature
molded overall.
It has following
features: Good weatherability, high rigid, good
insulation performance, etc.
--The
meter frame adopt top-quality steel plate once molding with
excellent mechanical
strength, stable structure and anti-impact.
--Voltage
components are used of all closed vacuum pouring coil by epoxy
resin. Current
components is used of double insulation
structure, has good electrical characteristics.
--The
type meter adopt magnetic thrust bottom bearing, upper oriented
bearing is made of
lubrication graphite bush and stainless
steel needle. It has following features: Small
abrasion, long life and minimal friction, etc.
--All
kinds of 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 disc and
convenient for adjusting by users.
--Standard
configuration 6 digits display by drum wheel mechanical counter, may
select 7
digits display by drum wheel mechanical
counter (Product Configuration code is PJ).
--Three
components measurem three phase four wire active energy
consumption.
Complying with standard IEC 62053-11.
--Standard
configuration for direct connect operation, type 16B wiring, we can
also choose
another type of wiring, and use
CT (Product Configuration code is PE), type 48B wiring,
and PT & CT (Product Configuration code is PF),
type 48B wiring
for operation.
--Standard
configuration extended terminal cover, it is for protecting use
electrical safety,
may select short terminal cover.
(Product Configuration code is OD).
