Three phase electricity meters A43 and A44
EQ meters in Bronze version from ABB
The compact and versatile EQ meters A43 and A44 are
three phase meters with full four quadrants measuring
meaning both active/reactive energy measurements and
import/export of energy. They can be used in most of
the common applications for reliable and trustworthy
metering of energy usage.
EQ meters A43 and A44 in Bronze version can be used
in stand-alone applications or metering network instal-
lations with the option of inbuilt M-Bus or Modbus.
General features
The A series meters are ideal for many applications and
installations. The meters support a wide voltage range as well
as a wide temperature range. The display is pixel-oriented
and can display up to four quantities at the same time.
Navigating the meter is easily done via the push-buttons
below the display. To configure the meter settings, the set
button must be accessed and this button is protected against
unauthorized use when the transparent lid on the front of the
meter is closed and sealed. The power consumption of the
meter is very low, less than 0.8 VA, makes them economical
in the long run - an important feature especially for large me-
ter populations.
Communication
Data from A43 and A44 in Bronze version can be collected
via pulse output or serial communication. The meters are
equipped with a transistor output for 5-40 VDC external
supply. It can be used for pulses proportionally to the mea-
sured energy or various alarms. The meters are also available
with built-in serial communication interfaces for Modbus RTU
(RS-485) or M-Bus as options.
Import and export measurements
B21 Bronze version measures the energy flowing both in (im-
ported) and out (exported) through the meter and saves the
energy in separate registers.
Approvals
The A43 and A44 meters are type approved according to IEC
as well as type approved and verified according to MID.
MID is the Measure Instruments Directive 2004/22/EC from
European Commission. The type approval is according to
standards that covers all relevant technical aspects of the
meter. These include climate conditions, electromagnetic
compatibility (EMC), electrical requirements, mechanical re-
quirements and accuracy.
Instrumentation
The A43 and A44 meters in Bronze version support reading of
instrument values.
A large number of electrical properties can be read.
• Active power - Total and per phase
• Reactive power - Total and per phase
• Apparent poser - Total and per phase
• Current
• Voltage
• Power factor
• Frequency
