3-phase power monitoring module
Analog input module from Opto 22 measures three-phase ac voltage and current, helping companies manage power quality and energy consumption.
A new analog input module from Opto 22 measures and monitors three-phase ac voltage and current, helping companies manage power quality and energy consumption.ulating equipment and facility power consumption. The module monitors up to 14 parameters of data relating to power generation and consumption. From these figures, other variables such as power factor can be determined.
For its six wired input channels, the Snap-AIPM-3 has a recommended input range of 85-250 Vac RMS or 0-10 ac A RMS. The module offers 10 mV of resolution with accuracy of +/- 0.2 volts for voltage inputs, and 400 microamps of resolution with accuracy of +/- 8 mA for current inputs. Significantly, the company says, Snap-AIPM-3 can also monitor ac line currents greater than 10 A using a standard 5A current transformer of suitable ratio.
The Snap-AIPM-3 is guaranteed for life, transformer isolated and, like all Opto 22 Snap modules, is optically isolated from the equipment and devices it connects to, as well as from other modules that may reside on a shared I/O rack. www.opto22.com
