Power monitoring solution

21 November 2017

Carlo Gavazzi’s WM50 power monitoring solution is said to reduce installation time by up to 75% when compared to existing solutions.

The WM50 is a multichannel power analyser offering Branch Circuit Power Monitoring for up to 96 channels in any combination of three-phase and single-phase loads or two-phase and single phase loads using the TCD12 split core current sensors.   

Made up of three components, the base unit provides a wide backlit LCD touch screen display to configure the system, view measurements and manages sixteen virtual alarms. There are two optional modules, one for digital I/O and the other for communication.   The WM50 features a modular sandwich style design, which provides up to 70% space saving behind the panel. Users simply snap additional modules to the rear of the meter by stacking and securing them to provide digital I/O and communication using either Modbus RTU or Modbus TCP/IP. 

Accuracy is ±0.2% RDG current and voltage, and the meter is rated equivalent to class 0.5S(kWh) according EN62053-22 measuring all the mains electrical variable, including the harmonic distortion (THD and single harmonics up to 32nd harmonic) of current and voltage.  Together with 10 digits for total energy counting of active and reactive imported and exported energy total kWh and kvarh and partial kWh and Kvarh viewing up to 6 energy tariffs.

The free proprietary UCS configuration software (desktop or mobile version) allows for quick system configuration and diagnostics. Alternatively, an optical port is available for quick analyser configuration using OptoProg accessory module (Carlo Gavazzi).

Applications run from cost allocation and control to critical load applications such as data centres and hospitals where high reliability and extreme measurement precision is required for monitoring of any single branch of the distribution system.
