Power analyser UMG 605

Added value through additional functions

Thanks to state-of-the-art digital signal processor, it is possible to offer the power quality analyser UMG 605 at a very reasonable price. The high sampling rate enables a continuous measurement of more than 2000 measured values per measurement cycle (200ms). The UMG 605 power quality analyser serves the purpose of continuous monitoring of the power quality e.g. in accordance with EN 50160. This serves the purpose of monitoring the supply power quality from the energy supply side. The UMG 605 can also be used in applications for failure analysis on the consumer side and is also used as a preventative measure for network perturbations.

Modbus gateway: the affordable connection of units without an Ethernet interface

With the Modbus gateway function, simple Modbus RTU-units can be connected to the Ethernet using the UMG 605. For example, the UMG 605 can be used simultaneously as a gateway for subordinate measurement points or older units which already exist in the installation. Each unit with a Modbus RTU interface can be connected, where the data format and function codes match up. Data can be marked and scaled.

High-speed Modbus

The device of the UMG 605 series can transfer data between the units using the RS485 interface at a speed of up to 921.5 kB/s.

 

Applications

The power quality analyser which is equipped with 4 current and voltage inputs collects and digitalises the effective values (True RMS) from currents and voltages in 40-70Hz (15-440Hz) networks. The integrated microprocessor calculates the electrical parameters from the sampling values. The relevant voltage can be defined as a phase-neutral or a phase-phase voltage for measurement in a three-phase system. The voltage serves the UMG 605 as a reference voltage for harmonic measurement, transient and event recording and for the flicker meter. A nominal current can be set using this for the measurement of electrical current events. However, it is generally used for measuring the current in the neutral or PE conductor or used for measuring a voltage difference between N and PE.

DIN rail mounting (6TE): reduction of installation costs

Measurement equipment is usually installed in the low voltage main distribution as an integral measurement instrument for the switchgear cabinet door. Installation and connection costs are significantly reduced by the installation of the UMG 605 on a 35mm DIN rail. This means that the panel cut-out and wiring to the cabinet door is no longer necessary. In order to make use of the extensive functions of modern measuring equipment, the interconnection and central analysis of the data plays an important role. This means that the on-site display generally serves the purpose of the initialisation and service only. 

The decidedly compact UMG 605 is suitable for installation in low voltage main distribution panels and machines as well as in installation distribution boards which is particularly of interest for applications in building services engineering, information technology and data centres.

Modern communication architecture through Ethernet: affordable, rapid and safe communication 

The costs for installation and communication (e.g. periphery for field buses) often surpass the costs of the measurement devices. By connecting the equipment to an existing Ethernet system, a fast, optimally priced and reliable communication system can be developed. Additional interfaces allow the integration of power analysers in PLC systems or in central building management systems. The use of open architecture offers the user a high amount of flexibility.

The e-mail and homepage inform you wherever you are… 

Who hasn’t experienced it before? You are hardly through the door and the telephone is already ringing. There are problems in production, computers are crashing and the energy supplies are lost. 

You have direct access to the extremely high performance homepage of the UMG 605 with a web browser and an IP address. Extensive information is already available to you on the homepage. Online data are available together with historical data and graphs recording events. The homepage can be used to directly convert the rates into costs and be exported as a csv file or printed. As an alternative, you can let yourself be informed by e-mail anywhere in the world if your energy supply becomes overloaded, if short-term interruptions to the voltage supplies bring your production processes to a standstill or unauthorised harmonics reduce the lifespan of equipment. 

The application possibilities are endless.
