Product leaflet 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 dardards that covers all rds that covers all relevant technical aspects of the meterelevant technical aspects of the meter.. The A series meters are ideal for many applications and These include climate conditions, electrThese include climate conditions, electromagnetic compatibilityomagnetic compatibility installations. The meters support a wide voltage range as well (EMC), electrical requirements, mechanical requirements and as a wide temperature range. The display is pixel-oriented accuracy. and can display up to four quantities at the same time. Navigating the meter is easily done via the push-buttons Instrumentation below the display. To configure the meter settings, the set The A41 and A42 meters in Bronze version support reading of button must be accessed and this button is protected against instrument values. unauthorized use when the transparent lid on the front of the A large number of electrical properties can be read. meter is closed and sealed. The power consumption of the Active power - Total and per phase meter is very low, less than 0.8 VA, makes them economical Reactive power - Total and per phase in the long run - an important feature especially for large Apparent power - Total and per phase meter populations. Current Voltage Communication Power factor Data from A41 and A42 in Bronze version can be collected Frequency via pulse output or serial communication. The meters are equipped with a transistor output for 5-40 VDC external Ordering details supply. It can be used for pulses proportionally to the mea- sured energy or various alarms. The meters are also available 80 A direct connected, 4 DIN with built-in serial communication interfaces for Modbus RTU Voltage V Communication Type Order code Weight 1 pc (RS-485) or M-Bus as options.
