Thanks to its isolated RS-485 Modbus RTU communication port, the device is free from ground potential difference issues. Measured parameters are safely transferred to factory and building automation systems.

The power supply of the unit is isolated, thus the same device can be used in both 2307400V and 120/208V systems.

The graphic screen allows display of waveforms and harmonic analysis graphs.

Various display screens can be scrolled automatically. The user configurable screen can be set to display any measured parameter, transforming the unit into a custom designed measurement panel.
The unit fits into a standard 92x92mm panel opening.
