Product Information
Full details
The Janitza UMG 104 is a precision-engineered power quality analyzer designed for facility managers, electrical engineers, and energy auditors who require granular monitoring of complex electrical networks. Its primary strength lies in its rapid 500 MHz DSP and 20 kHz sampling rate, which provides highly accurate data for identifying production failures and energy inefficiencies. While it offers industry-leading diagnostic capabilities, it requires a dedicated understanding of industrial power monitoring protocols for initial configuration and data integration.

FAQs
Can the UMG 104 monitor DC power?
The UMG 104 is primarily designed for AC network analysis, focusing on electrical parameters and harmonics within standard power grids.
How do I access the 800+ recorded values?
Data is retrieved via the device's communication interface using compatible Janitza software or third-party SCADA systems.
Is it possible to track transients with this device?
Yes, the 20 kHz sampling rate allows for the detection of significant power quality events and transients.
Does the unit need external power?
Yes, the device requires an auxiliary power supply to function, typically tapped from the monitored source or a dedicated rail.
Can I use the UMG 104 outdoors?
The device must be installed inside an appropriate IP-rated protective enclosure if used in outdoor or dusty environments.
Troubleshooting
Device is not communicating with central storage
Verify the network cable connection, check IP addressing settings in the device configuration, and ensure the baud rate matches your gateway.
Inaccurate current readings
Ensure the current transformers are properly clamped and the phase orientation is correct according to the device wiring diagram.
Missing harmonic data
Confirm that the sampling settings in the configuration software have not been capped and that the firmware is updated to the latest version.
Pros and Cons
Pros
- Extremely high sampling rate for accurate transient detection
- Comprehensive harmonic analysis up to the 40th order
- Powerful 500 MHz DSP for instant data processing
- Wide array of logged parameters (over 800 values)

Setup, Compatibility & Care
Installation of the UMG 104 should be performed by a qualified electrician, as it involves integration with live voltage inputs and current transformers. Ensure the unit is mounted in a standard control cabinet environment with adequate ventilation. Compatibility depends on the communication protocol utilized; users should verify that their central storage or BMS (Building Management System) supports the UMG 104 communication standard. For care, keep the ventilation slots clear of dust and debris, and perform periodic firmware checks to ensure the device remains compliant with current power quality monitoring standards.
