Single phase electricity meters A41 and A42

EQ meters in Bronze version from ABB

The compact and versatile EQ meters A41 and A42 are

single 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 A41 and A42 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

meter populations.

Communication

Data from A41 and A42 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 A41 and A42 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 Euro-

pean Commission. The type approval is according to stan-

dards that covers all relevant technical aspects of the meter.

These include climate conditions, electromagnetic compatibility

(EMC), electrical requirements, mechanical requirements and

accuracy.

Instrumentation

The A41 and A42 meters in Bronze version support reading of

instrument values.

A large number of electrical properties can be read.
