The SNAP-AIPM-3 and SNAP-AIPM-3V can each monitor 480 Vac, 3-phase electrical equipment without need for a potential transformer.
Opto 22 has enhanced the capabilities of its most widely used power monitoring modules to give clients broader voltage input ranges and better resolution for their three-phase power monitoring and energy management applications. The SNAP-AIPM-3 and SNAP-AIPM-3V can each monitor 480 Vac, 3-phase electrical equipment without need for a potential transformer. Both modules accept voltage inputs up to 300 Vac, so 277 volt line-to-neutral signals from lighting systems and other equipment can be wired directly to the module. Eliminating the transformers to step down higher voltages significantly reduces installation cost and complexity.
Additionally, the SNAP-AIPM-3 now accepts current inputs from 0 to 5 A. This improvement doubles the module’s current input resolution, letting clients observe changes in their power usage in higher detail. The SNAP-AIPM-3 is compatible with the most common current transformers-which step down a primary current to a secondary of 5 amps or less-making engineering unit conversion and scaling for the SNAP-AIPM-3 easier as well.
In energy monitoring applications, the SNAP-AIPM-3 and the SNAP-AIPM-3V let building managers, maintenance engineers, and other business stakeholders monitor three-phase equipment power in their facilities. Each module returns up to 14 channels of data including volts, amps, volt-amps, and true power for all three phases, plus true power sums. Clients can use the modules as part of a SNAP PAC System to correlate their energy usage with specific business operations. At that point, real-time data can be used to identify problems and design energy management initiatives to reduce energy costs.
System integrators can use the modules to develop control systems for commercial and industrial clients to monitor and regulate 3-phase power consumption so they can reduce energy usage, avoid peak pricing charges, and lower energy costs. For OEMs, the modules provide a simple and straightforward method for integrating power monitoring and energy consumption into their machine control, establishing an important differentiator in their offering.
For its six wired input channels, the SNAP-AIPM-3 has input ranges of 85 to 300 Vac RMS and 0 to 5 ac Amps RMS. The module offers 12 mV resolution with accuracy of ±0.2 V for voltage inputs, and 200 mA resolution, ± 4 mA for current inputs.
For its six wired inputs, the SNAP-AIPM-3V has input ranges of 85 to 300 Vac RMS and 0-0.333 Vac from current transformers with a 333 millivolt secondary. Accuracy is ±0.2 V for inputs and 13.3 microV ac for current inputs.
Both modules are guaranteed for life, transformer isolated, and (like all Opto 22 SNAP I/O modules) optically isolated from the equipment and devices they connect to, as well as from other modules on a shared I/O rack. SNAP-AIPM-3 and SNAP-AIPM-3V are available at a list price of $495.00 USD each.
