Multichannel power analyser for single, two and three-phase systems

WM50 is a multichannel power analyser for single,two and three-phase systems. Using TCD12 split core current sensors, it can monitor up to 96 single phase loads or any combination of single and three-phase loads or two and single-phase loads for a maximum of 96 channels.

The system can be set up, measurements viewed and up to 16 alarms managed from WM50 and UCS.

Main unit functions can be expanded with a maximum of two of the following available modules – digital input/output module, analog input module and communication module.

Benefits

  • Low measurement cost per channel. You can monitor up to 96 current channels with a single analyser thanks to the specific 12-channel current sensors.
  • Reduced installation time and errors. It is equipped with detachable terminals for all connections. It connects to 12-channel current sensors with proprietary cables. The clips supplied with the sensors ensure that cables are always in order during installation.
  • Scalability. WM50 can be integrated with accessory modules to expand its control and communication capacity.
  • Disturbance immunity. Digital communications between current sensors and WM50 ensure excellent disturbance immunity.
  • Granular analysis. It provides total and single load measurements (up to 96 current channels).
  • Clarity. The wide backlit LCD display clearly shows the measurements and the configuration parameter values.
  • Quick configuration. The proprietary UCS configuration software (desktop or mobile version) is free and permits quick system configuration and diagnostics. An optical port is available for quick analyser configuration using OptoProg (CARLO GAVAZZI).

Applications

WM50 with TCD12 current sensors is connected directly on output from the circuit breaker present in switchboards for simultaneous monitoring of multiple single or three-phase loads in low voltage systems.

In a data centre, WM50 can monitor up to 96 channels and thus ensures that an entire Power Distribution Unit (PDU) is monitored.

In other contexts, with critical loads such as hospitals, food storage or industrial production systems, WM50 guarantees high reliability and extreme measurement precision.

Energy Management Integrated Web-Based Solution for Energy Management Type VMU-C

VMU-C is a combination of modules which performs the monitoring of an Energy Management installation.

The core unit is VMU-C gathering data from up to 32 energy meters; the meters can be both AC or DC meters.

In addition to the data-logging, it also performs the management of local or remote (via VMU-M) VMU-O “I/O unit” and/or VMU-P “Environment variable unit” and provides an FTP push functionality.

VMU-C can also provide, by means of the VMU-O modules, relay alarm contacts and digital inputs (e.g. for status indication to sense the tripping of an automatic switch).

The VMU-W unit has the task of transmitting, with wireless modem technology, all the data when a wired LAN or Internet access is not available.

The FTP push function enables an FTP based communication from VMU-C to an external FTP server (owned by the enduser) to transmit, in a simple and standard way, a predefined set of data (using CVS format).

In this case, data is gathered and logged by VMU-C from the energy meters and VMU modules in the field and, following a schedule or a trigger, is grouped into a file and uploaded to the defined FTP server.

The upload action is repeated in case of failure.

In addition to the protocol, VMU-C can communicate data in M2M (machine to machine) scenario also via HTTP protocol.

Main Features

  • Integrated modular local monitoring system for Energy Management plants based on Webserver & FTP/push capability
  • Up to 8 DIN modules configuration equivalent to 140mm width
  • VMU-C EM can manage on RS485 bus up to 32 Energy Meters or Power Analysers
  • VMU-C EM can manage on local bus 1 VMU-W modem unit
  • VMU-C EM can manage on local bus up to 4 VMU units & up to 10 VMU-M based arrays on RS485 bus
  • Any VMU-M based arrays can manage up to max 1 VMU-P unit & max 3 VMU-O unit
