Main features of the UMG 103-CBM

  • Harmonics

    Harmonics are caused by equipment with non-linear characteristics, such as transformers operated in saturation, energy-saving lamps, frequency converters and power electronics. They burden the grid with additional currents and can affect or even destroy equipment. These grid perturbations can be detected and documented using power quality analyzers.

  • Modbus interface

    Many UMG measurement devices have an RS485 interface with Modbus RTU protocol, which enables extremely cost-effective networking. It is characterized by a simple topology structure and insensitivity to EMC interference. Communication between the transmitter and receiver is wired via a shielded, twisted pair cable.

  • GridVis®

    GridVis® is a comprehensive and scalable software for setting up an energy monitoring system and for monitoring power quality. It is used for programming and configuring many UMG measurement devices as well as for reading, processing and analyzing measurement data. Typical applications are energy supply, industrial plants, facility management, etc.

  • Limit value monitoring

    Limit value monitoring can be assigned to both alarm management and switching operations. Corresponding UMG measuring devices have digital outputs that are also suitable as switching outputs. This allows certain reactions to be automated if a threshold value is exceeded or not reached.

Areas of application

Large measurement data memory for even more data security

Qualified statements about energy consumption and voltage quality cannot be obtained with measurements that are limited exclusively to the feed-in point. If you want to find sources of interference or energy wasters, you have to collect data at many points in the network, i.e. the granularity (resolution) of the measurement is crucial. But this is often a question of space and cost.

The new UMG 103-CBM is an ideal solution for this task. The extremely compact and inexpensive universal measuring device only requires a width of 71.5 mm on the top-hat rail and therefore fits easily into any installation distribution board. In addition to a large number of energy values and electrical measured values, it offers a variety of additional functions, such as the measurement of harmonics, storage of minimum and maximum values, operating hours counter and bimetal function. The UMG 103-CBM can be operated as a slave on a higher-level device, such as the UMG 604E, or connected directly to a PC.

Local data backup with clock | battery | memory

The Janitza UMG 103-CBM is based on the tried and tested technology of the UMG 103. With a clock, battery and measurement data memory, it becomes a device that opens up completely new applications. On the one hand, data security is significantly increased. This is highly relevant if energy data is recorded separately for individual parts of the company or customers. On the other hand, the device can be used as a stand-alone solution in areas where differentiated network monitoring was previously too complex.

Ideal for Industry 4.0 applications

Industry 4.0 – that means networking on the one hand and intelligent control systems deep into the system field on the other. What the sensors at the tip of a robot arm detect is transmitted to a development team on the other side of the world. This technology requires a power supply of the highest quality and reliability; real-time data processing does not tolerate voltage dips.

It is only logical not to monitor the energy supply with a multitude of instruments, but – in line with the philosophy of Industry 4.0 – to integrate it into a single, modern monitoring system.

The UMG 103-CBM is an ideal module for measurement data acquisition at the front line. Together with master devices (e.g. UMG 604E or UMG 96RM-E) and the GridVis® software, scalable solutions can be realized. All data is recorded centrally in a database and can be recorded and analyzed with GridVis®. This not only saves direct costs in purchasing, but also simplifies integration, training and service measures. As all information can be accessed via common, standardized interfaces, 3-in-1 monitoring fits perfectly into the Industry 4.0 concept.
