Janitza Electronics GmbHPower Quality Analyzers
UMG 509-PRO
DIN-rail power quality + RCM analyzer
The UMG 509-PRO is a DIN-rail multifunction analyzer that tracks power-quality disturbances (harmonics, transients, voltage events) while simultaneously watching for abnormal residual/leakage current, effectively combining a power-quality recorder with an early-warning insulation/fire-safety monitor. It's positioned for continuous, unattended monitoring roles such as data centers, ISO 50001 programs, and remote facility monitoring.

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.
- Harmonic Filter SolutionsNonlinear loads such as frequency converters, rectifiers, UPS systems, power electronics equipment and arc furnaces can cause current and voltage harmonics on the network. High harmonic levels lead to overheating in transformers, cables and capacitors, to increased energy losses, to a risk of resonance and to unexpected failures in sensitive equipment. Harmonics are reduced with active or passive harmonic filter solutions selected according to the facility's load structure and harmonic spectrum. Passive harmonic filters are effective at reducing specific harmonic components, while active harmonic filters compensate harmonics in real time under variable load conditions, providing dynamic filtering. At EPKOM we determine the filter type and capacity that suits the facility from power quality measurements and harmonic analysis, and engineer our solutions taking IEEE 519 and the relevant IEC/EN standards into account. This reduces harmonic levels, protects equipment and allows the electrical system to run more safely and efficiently.
