single phase electromechanical front board installed active
energy meter
Application |
|
Model
DEM191QK single phase electromechanical front board installed active
energy meter is a kind of new style single
phase two wire
active energy meter which has several properties of anti-steal, it is on
the basis of original DEM073 single
phase
electromechanical meter, and fully absorb new technology about
electromechanical meter from domestic and
abroad, and
developed 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.

single phase electromechanical front board installed active
energy meter
Function and features: |
|
-single phase electromechanical front board installed active
energy meter- It
has a group of supplementary coil more than ordinary meter to be
complicated with its
measuring circuits.
-single phase electromechanical front board installed active
energy meter-It
can resist stealing power supply as following: to earth, reverse
connection, separate
current, from condenser.
-single phase electromechanical front board installed active
energy meter-Its
function and connection circuits are the same as ordinary meter
under the correct
operating.
-single phase electromechanical front board installed active
energy meter-Front
board three fixed installation, the base of the meter and the
terminal block is made of
exceuent quality bakelite material
which is moisture-resistant, fire-retardant, high
temperature molded overall. The cover are is also made
of bakelite
material and has a
transparent glass window. It has following features:
good weatherability, high rigid,
specious appearance, etc.
-single phase electromechanical front board installed active
energy meter-Standard
configuration bottom bearing is used of double jewel bearing,
upperoriented
bearing is made of high wear resistance
copper alloy bush and stainless steel needle. It
has following features: long life and minimal friction,
etc.
you may select magnetic thrust
bearing (Product Configuration code is QE) or magnetic
suspension (Product
Configuration code is QQ).
-single phase electromechanical front board installed active
energy meter-Its
register is indirection and use the transmission ratio between
positive and negative,
Standard configuration 6 digits display
by drum wheel mechanical counter, may select 5
digits display by drum wheel mechanical counter
(Product Configuration
code is QH).
-single phase electromechanical front board installed active
energy meter-Standard
configuration without handle, you may select add a handle for
carrying the meter
conveniently. (Please specified
when ordering).
-single phase electromechanical front board installed active
energy meter-Single
component measureing single phase two wire active energy
consumption.
Complys with standard IEC 62053-11.
-single phase electromechanical front board installed active
energy meter-Direct
connect operation, there are two types you may select. Standard
configuration type
1B wiring, you may select type
1A wiring (Product Configuration code is QJ).
-single phase electromechanical front board installed active
energy meter-Exended
terminal cover, it is for protecting use electrical safety.
