The new PWRM10-01 and PWRM20-01 instrument class energy monitoring modules are the result of more than 35 years of experience in the process control industry. These DIN rail mounted, rugged, industrial modules provide a modern solution for a wide range of energy related applications such as energy metering systems, power quality monitoring, solar monitoring, process monitoring or predictive maintenance.
The two Dataforth modules PWRM10-01 and PWRM20-01 are universal, high-precision, compact and energy-autonomous IoT power meters that can be connected to three-phase and single-phase systems. The modules were developed specifically for retrofit applications in power distribution in industrial plants and buildings. The devices not only determine the current values for active, reactive and apparent power, but also time peak values, frequency and phase angle of the monitored power system. The extended operating temperature range of -40°C to +85°C also enables use in protected outdoor areas or in areas with higher temperatures. With a maximum error tolerance of only 0.2% in power measurement, the modules achieve very high measurement accuracy.
"The benefits offered by our new power monitoring modules are so significant and far-reaching," said Georg Haubner, Dataforth vice president of marketing and sales. "The numerous features of the PWRM10-01 and PWRM20-01 modules combined with their ease of use make measuring power quality, monitoring energy consumption, or determining machine health and other performance-related data a simple process."
The DIN-rail mounted units feature plug-in terminal blocks for voltage and current, simplifying setup and maintenance, and the small format takes up little space in control cabinets. The PWRM10-01 module can be connected to voltages from 85-265VAC, 50/60Hz and is powered by one of the lines itself. For higher voltage systems, the PWRM20-01 module can be connected to voltages up to 525VAC, 50/60Hz and is powered by one of the lines. The power consumption of the modules is low and does not affect the measured power and energy. The measuring ranges of the modules can be easily extended using external voltage and current transformers. The devices are set up via the network interface and the integrated web server. If the measurement data is to be integrated into an existing monitoring system, an http API is available.
