DETAILED DESCRIPTION

WM50
Α multichannel power analyzer for 1, 2 or 3 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 analyzer 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 he 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 analyzer configuration using OptoProg (CARLO GAVAZZI).portfolio.
