Modbus RTU
Janitza UMG511
Janitza
Overview
The Janitza UMG 511 is a three-phase power quality analyzer for industrial plants and commercial buildings, used for continuous electrical monitoring at the grid connection point or sub-distribution level. This Modbus RTU template reads per-phase voltage, current, active power, and reactive power across all three phases, plus total active power, total reactive power, grid frequency, and cumulative active consumption and production energy counters. With these registers in your ModbusCloud portal, you can track load balance, detect power quality deviations, and verify energy flows without additional software.
Use cases
- Monitor per-phase voltage on L1, L2, and L3 to detect supply imbalances before equipment is damaged.
- Track cumulative active consumption and production energy to generate tenant or cost-center sub-metering reports.
- Alert on total reactive power deviations to identify capacitor bank failures or lagging load conditions.
- Compare per-phase active power readings to verify even load distribution across the three phases.
