ACM3P : Murata Power Solutions Launches Compact 3-Phase AC Digital Ammeter with Built-in Current Transformers
Accepting a universal 85 - 264 VAC 47 – 63 Hz supply input the ACM3P series is suitable for 3-phase current monitoring requirements worldwide. Accommodated in a single vibration resistant polycarbonate housing measuring just 53.3 x 36.3 x 28.2 mm, the ammeter is ideal for mounting in vertical ‘0U’ or horizontal ‘1U’ rack spaces. The ACM3P uses a 9.2 mm low power LED display that is available in a choice of red, blue or green. The large and bright LEDs makes it easy to read the display from as far as 5 meters. A front panel selector switch allows the user to quickly cycle through each of the three phase currents under measurement.
The ACM3P series is suitable for a broad range of test, instrumentation and energy metering applications. A low power microcontroller is used for measurement, and together with low power LED displays ensures that the ammeter consumes very little power, typically less than 0.5 W from a 240 VAC supply. No additional components are required making the ammeter quick and easy to install.
