PRODUCT OVERVIEW
Built for Electrical Measurement
The UMT 1 is a measuring transformer for true RMS values. It can monitor a three-phase electrical system using voltage and current measuring inputs. The measured values are processed internally and shown on the two-line LC display.
Different UMT 1 packages provide additional functionality, including configurable analog outputs and communication interfaces for connection to higher-level control systems.
