OVERVIEW:

All-in-one power analyzer

• The Janitza UMG 801 energy measurement device offers various communication interfaces and enables direct data transmission to higher-level systems via OPC UA, eliminating the need for costly integration.
• The modularly expandable UMG 801 is ideally suited for the complete acquisition of an energy management system (e.g. ISO 50001). You gain transparency about energy consumption and energy costs at all measurement levels. In addition, critical deviations in power quality as well as residual currents (RCM), which load or even systems at risk, can be detected.
• Future-proof investment: the measuring points can be subsequently extended to up to 92 measurement channels thanks to easily integrated current measuring modules.

BENEFITS:

• Space-saving, compact system
• The measuring modules do not require an additional power supply
• Shorter assembly time due to simple click system
• Reduced error sources thanks to plug & play solution
• Minimum costs per additional current measurement channel
• No additional voltage measurement necessary

FEATURES:

All-in-one device

• The basic device has: 8 current measurement channels with 1 A or 5 A inputs and 4 multifunction channels, optionally configurable as RCM, temperature measurement channels or additional current measurement channels
• Extensive measurement data memory with 4 GB for storage of measurement data
• Two groups with four digital IOs each (tariff changeover and pulse input, logic states)
• Analog output (DC 0/4-20 mA)

High-precision measurement

• High sampling frequency (51.2 kHz voltage)
• 1024 Samples for the voltage measurement
• High measurement accuracy on all channels (V: 0.2% / A: 0.2% / kWh: class 0.2)
• Maximum safety: 1000 V CAT III
• Extensive power quality parameters: Voltage up to 127th harmonic and interharmonics – THD-U and THD-I, unbalance, event and transient detection

Visualizing, documenting and analyzing

• Comprehensive options for visualizing, analyzing and documenting energy measurement data (GridVis® software)
• Integrated automatic report generation (GridVis® software)
• Integrated color graphic display for visualization and intuitive configuration on site

Managing and using data

• Various interfaces for simultaneous use: 2 Ethernet interfaces and RS485 interface for data readout and can be used as gateway
• Comprehensive protocols and services (OPC UA and Modbus)

Profit from OPC UA

• Easy integration of measurement data from the basic device and measurement modules into higher-level systems (e.g. building control systems, SCADA systems)
• Cyber security: Integrated security mechanisms to protect against unauthorized access and misuse
• Configuration of the entire measuring system via OPC UA
• Future-proof software architecture as the OPC UA standard evolves with new application

Future-proof investment

• Modular extension of the measuring points by measuring modules
• Open and future-proof communication through various interfaces and OPC UA Server
• IPv4 and IPv6 Ethernet IP addresses

Flexible use

• Multifunction channels are available and offer flexible options depending on the application required: RCM, temperature or current measurement

Minimum integration costs

• Easy integration into a higher- level system through open communication architecture via OPC UA standard (e.g. GLT, SCADA and ERP applications)
• Versatile interfaces that can be used simultaneously
• Gateway functionality for integrating additional devices e.g. Janitza UMGs from downstream measurement levels

Maximum data security

• Secure communication through OPC UA security structures
• Data storage (redundancy) provided by the basic device’s onboard memory

Power quality

• Capture, analysis and documen­tation of disturbance variables, e.g. harmonics current
• Event and transient detection with storage in PQDiff and Comtrade,
• Comprehensive visu­alization in the event browser
