Product leaflet 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 InstrumentationInstrumentation The A43 and A44 meters in BrThe A43 and A44 meters in Bronze version support ronze version support reading ofeading of The A series meters are ideal for many applications and instrument values.instrument values. installations. The meters support a wide voltage range as well A large number of electrical properties can be read. as a wide temperature range. The display is pixel-oriented and can display up to four quantities at the same time. Active power - Total and per phase Reactive power - Total and per phase Navigating the meter is easily done via the push-buttons Apparent poser - Total and per phase below the display. To configure the meter settings, the set Current button must be accessed and this button is protected against Voltage unauthorized use when the transparent lid on the front of the Power factor meter is closed and sealed. The power consumption of the Frequency meter is very low, less than 0.8 VA, makes them economical in the long run - an important feature especially for large me- Ordering details ter populations. 80 A direct connected, 7 DIN Communication Voltage V Communication Type Order code Weight Data from A43 and A44 in Bronze version can be collected 1 pc via pulse output or serial communication.
