2.0 Description and Documentation
Energy Monitoring Modules PWRM10-01 and PWRM20-01 are IoT, universal, high accuracy,
compact, self-powered, electrical energy measurement devices that interface to three-phase and
single-phase systems. The modules are specifically designed for heavy-duty industrial and
commercial installations and retrofit applications, providing a wide range of highly accurate power
and energy measurements over an operating temperature range of -40°C to +85°C.
The DIN rail mounted enclosures have pluggable terminal blocks for connecting to phase voltages
and phase currents which simplifies setup and maintenance. Both modules have a small form factor
which occupies less space in control cabinets than other measurement solutions. The PWRM10-01
module interfaces to phase voltages of 85 –265VAC, 50/60Hz and is self-powered from any of the
three phases. For higher voltage systems, the PWRM20-01 module interfaces to phase voltages of
85 –525VAC, 50/60Hz and is self-powered from any of the three phases. Both modules can interface
to higher phase voltages with the use of voltage transformers and scaling configured in the module.
Power consumption is low and does not affect measured power and energy.
Phase current inputs have an industry standard range of 0.333VAC full scale. The modules are
configurable to use an external shunt, current transformer, or Rogowski Coil to measure phase
currents directly or non-contact.
The PWRM10-01 and PWRM20-01 modules measure and report a wide range of electrical energy
parameters which include, but are not limited to:
•RMS Voltages and Currents
•Phase Angles
•Line Periods
•Instantaneous Total Active Power
•Instantaneous Total Apparent Power
•Fundamental Active Power
•Power Factors
•Total Active Energy
•Fundamental Active Energy
•Fundamental Reactive Energy
•Reactive Energy
•Harmonics
•Power Quality –Configurable Events Monitor and Post Notifications for:
▪Over-Voltage
▪Over-Current
▪Sag
Real-time data from the module is accessed via an Ethernet port using the HTTP API or a standard
web browser on a host computer, smart phone, or tablet. Data logging is user configurable and once
parameters and ranges are selected, the data is automatically downloaded and stored.
With the ease of use and many features of the PWRM10-01 and PWRM20-01 modules, measuring
power quality, monitoring energy consumption, determining machine health, and other powerful data
analyses become simple operations.
