Janitza UMG 96-PA Universal Measuring Device / Power Quality Analyser (5232001)

Accurate energy monitoring and power quality analysis in industrial and commercial electrical installations require a reliable, high-precision measuring device. The Janitza UMG 96-PA is a panel-mounted universal measuring device that captures electrical parameters in three-phase systems, enabling detailed energy management and power quality assessment.

Who is it for

This device is intended for electrical engineers, facility managers, and energy consultants who need to monitor power consumption, analyse harmonics, and ensure power quality in low-voltage distribution systems. It suits applications such as machine monitoring, sub-metering, and energy audits.

Main features

• Measures voltage, current, frequency, power (kW, kVA, kVAr), energy (kWh, kVAh, kVArh), power factor, harmonics up to the 15th order, and total harmonic distortion (THD).
• High accuracy class 0.5S for active energy according to IEC 62053-22.
• RS485 interface with Modbus RTU protocol for integration into energy management systems.
• Backlit LCD display for on-site reading of measured values.
• Two digital inputs and two digital outputs for pulse counting, alarm signalling, or control.
• Internal 128 MB flash memory for data logging.
• Wide auxiliary voltage supply range: 95-240 V AC or 135-340 V DC.
