Why choose it

The UMG 96-S2 combines high-accuracy energy measurement with harmonic analysis and data logging in a compact 96 x 96 mm format. Its RS485 interface allows integration into energy management systems, and the two digital outputs can be configured for pulse counting or alarm signaling.

Ideal use cases

• Monitoring electrical consumption in industrial control panels
• Sub-metering in commercial buildings
• Power quality analysis in machine installations
• Energy data acquisition for ISO 50001 management systems

Good to know

The device requires external current transformers for current measurement. It is designed for panel mounting and is suitable for use in dry indoor environments. Configuration is done via the front panel or through Modbus RTU.
