Opto 22 SNAP-AIPM-3 and 3V power monitoring modules
June 07, 2011 - Opto 22 says it has enhanced the capabilities of its most widely used power monitoring modules to give customers broader voltage input ranges and better resolution for their three-phase power monitoring and energy management applications.

Now, the SNAP-AIPM-3 and 3V can each monitor 480vAC, 3-phase electrical equipment without requiring a potential transformer. Both modules accept voltage inputs up to 300vAC, and the AIPM-3 now accepts current inputs from 0-5 amps, which doubles the module’s current input resolution (allowing customers to observe changes in power usage in greater detail). In energy monitoring applications, the AIPM-3 and AIPM-3V return up to 14 channels of data, including volts, amps, volt-amps, and true power for all three phases, plus true power sums. Customers can use the modules as part of a SNAP PAC System to correlate their energy usage with specific business operations.
