Energy Monitoring Modules PWRM module family are IoT capable, 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 installation 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 phase voltages and phase currents which simplifies setup and maintenance. PWRM modules have a small form factor which occupies less space in control cabinets than other measurement solutions.
Modules are self-powered from any of the three phases. Power consumption is low and does not affect measured power and energy. PWRM modules can interface to higher phase voltages with the use of voltage transformers and scaling configured in the module.
Phase current inputs have an industry standard range of 0 - 0.333VAC. The modules are configurable to use an external shunt, current transformer, or Rogowski Coil to measure phase currents directly or non-contact.
The PWRM module family measure and report a wide range of electrical energy parameters which include, but are not limited to:
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 PWRM module family, measuring power quality, monitoring energy consumption to reduce costs, determining machine health, and other powerful data analyses become simple operations.
