Multifunction Power measuring device

Janitza UMG 96 L is a universal digital power meter designed for continuous measurement and monitoring of electrical parameters in three-phase systems. It is ideal for use in low-voltage switchgear and distribution panels, supporting both residential and industrial applications.

Key Features:

• Measurement Functions: Measures voltage, current, active power (kW), reactive power (kVar), apparent power (kVA), frequency, power factor (cos φ), and energy (kWh, kVarh) in three-phase systems (with or without neutral).

• Current Measurement: Via external current transformers (CTs), typically ../5A or ../1A.

• Voltage Measurement: Up to 500 V AC L-N or 870 V AC L-L (depending on version); suitable for direct connection in low-voltage networks.

• Display: LCD with backlighting for clear presentation of all measured values.

• Mounting: Panel mount (96 × 96 mm), easy installation in switchboards.

• Sampling and Accuracy: True RMS (TRMS) measurement, high immunity to interference, and suitable for continuous, unsupervised operation.

• Power Supply: Powered directly from the measured phase (no separate auxiliary supply required).

• Operating Temperature: -10°C to +55°C.

• Memory: Stores minimum and maximum values for key parameters.

• Interfaces: Some variants offer RS-485 (Modbus RTU) communication for integration into energy management systems

• Applications:

  • Replacement for multiple analogue instruments (ammeter, voltmeter, power meter, frequency meter, etc.)

  • Energy monitoring and load analysis

  • Suitable for low- and medium-voltage distribution boards
