Model
DEM082WA three phase three 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 D86 three
phase electromechanical meter,
and fully absorb
new technology about electromechanical meter from domestic and abroad.
The meter completely
accords 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 three wire AC
electricity net, it is use for setting indoor or out door meter box.

Function and features: |
|
-- Front
board three fixed installation, the cover is made of PC material
which is transparent
and anti-UV molded overall, the
base of the meter is made of black glass fiber which can
be fire-retardant and is enhanced PC material, the
terminal
block is made of exceuent
quality bakelite material which is moisture-resistant,
fire-retardant, high temperature
molded overall. It has following features: good
weatherability, anti-impact, specious
appearance, etc.
--The
meter frame is adopt aluminum molding with excellent mechanical
strength, stable
structure and anti-impact.
--Voltage
components and current components are used of double insulation
structure,
switch has good electrical characteristics.
--Standard
configuration the meter is adopt magnetic thrust bottom bearing,
oriented
bearing is made of lubrication graphite
bush and stainless steel needle. It has following
features: small abrasion, long life and minimal
friction, etc.
--You
may select doule gem bearing (Product Configuration code is WM)
--All
kinds of error 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 5 digits display by drum wheel mechanical counter, you
may select
6 digits display by drum wheel
mechanical counter (Product Configuration code is WG).
--Standard
configuration without the device which can prevent retrograde, you
may select
additional the function of prevent
retrograde. (Please specified when ordering).
--Three
components measuring three phase four wire active energy
consumption. complys
with standard IEC 62053-11.
--Standard
configuration for direct connectting operation, type 16A wiring, we
can also
choose another type of wiring, and
use CT (Product Configuration code is WB), type 48A
wiring, and PT & CT (Product Configuration code is
WC), type
48A wiring for operation.
--Extension
terminals cover, it is for protecting use electrical safety.
