UMG 800
Modular energy analyzer
The UMG 800 is a modular metering platform rather than a single fixed device: you start with a compact DIN-rail base unit and physically snap on additional current-measurement, digital-I/O, or communication modules as monitoring needs grow. This makes it well suited to larger installations such as data centers, production plants, and substations where many feeders need metering from one coordinated system; a single base can expand up to 96 current channels and 182 digital inputs across a full modular system.
Key Features
- 01Plug-and-play modular architecture (current, digital-I/O, and communication modules)
- 02Scales from a single feeder to system-wide monitoring (up to ~96 current channels)
- 03Integrated web server; optional RD 96 remote display
- 0451.2 kHz voltage sampling, harmonics to the 63rd order, transients down to 18 µs
- 05125 comparators across 32 comparator groups for limit-value alarms
- 06Made in Germany, ISO 9001 (TÜV SÜD)
Applications
- Power Quality SolutionsPower quality problems such as harmonics, voltage sags and swells, flicker, transients and voltage unbalance can occur in electrical systems. They can arise from non-linear loads, sudden load changes, network events and the electrical structure of the facility itself. Poor power quality can cause overheating in equipment, nuisance tripping, energy losses, shorter equipment life and interruptions to production continuity. At EPKOM we use power quality analyzers to measure and monitor LV and MV systems, recording harmonics, voltage events and the other power quality parameters. We evaluate the resulting data against the relevant standards, such as EN 50160, IEC 61000 and IEEE 519, according to the measurement point and the scope of the application. Following measurement and analysis, we apply active and passive harmonic filters, SVG systems, compensation solutions and power quality monitoring systems according to the needs of the facility, helping the electrical infrastructure run more safely, efficiently and stably.
- Energy Monitoring SystemsEnergy monitoring systems measure and analyse electricity consumption continuously, at facility, feeder, department or machine level. Alongside electricity, other energy sources such as water, natural gas and compressed air can be tracked through the same system. Data from Janitza energy analyzers is collected centrally in the GridVis software, where consumption trends, load profiles and energy performance indicators can be followed. Automatic reporting and alarm functions make abnormal consumption and energy losses quick to identify. Energy monitoring systems help to allocate energy costs correctly, to identify inefficient points of consumption and to improve energy performance continuously. They also support ISO 50001 energy management processes and make it possible to track energy performance indicators such as PUE in data centers.
