Application |
|
Model
DEM071QB single phase mechanical front board installed active
energy meter is a kind of new style single
phase two wire
active energy meter, it is on the basis of original single 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 single phase
active energy meter stipulated in
International
standard IEC 62053-11. It can accurately and directly measure 50Hz or
60Hz active energy consumption
from single phase
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: |
|
-single phase mechanical front board installed active
energy meter- Front
board three holes fixed holes installation, 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
moistureresistant, fire-retardant,
high
temperature molded overall. It has following features:
Good weatherability, high rigid,
specious appearance, etc.
-single phase mechanical front board installed active
energy meter-The
meter frame adopt top-quality steel plate once molding with
excellent mechanical
strength, stable structure and anti-impact.
-single phase mechanical front board installed active
energy meter-Voltage
components is used of all closed vacuum pouring coil by epoxy resin.
Current
components is used of double insulation
structure, has good electrical characterupper.
-single phase mechanical front board installed active
energy meter-The
meter 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.
-single phase mechanical front board installed active
energy meter-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.
-single phase mechanical front board installed active
energy meter-Standard
configuration 5 digits display by drum wheel mechanical counter, may
select 6
digits display by drum wheel mechanical
counter (Product Configuration code is QE).
-single phase mechanical front board installed active
energy meter-Single
component measure single phase two wire active energy consumption.
Complying
with standard IEC 62053-11.
-single phase mechanical front board installed active
energy meter-Direct
connect operation, there are two types you may select. Standard
configuration type
1B wiring, may select type 1A
wiring (Product Configuration code is QA).
-single phase mechanical front board installed active
energy meter-Standard
configuration short terminal cover, may select extended terminal
cover, it is for
protecting use electrical safety.
(Product Configuration code is PB). |
