Product Overview

The Omron KM-N1-FLK is a compact, panel-mount small power monitor designed for single-phase alternating current applications. This energy monitoring device provides comprehensive measurement of electrical parameters including voltage, current, active power, and cumulative energy consumption. The KM-N1-FLK features RS-485 communication supporting both CompoWay/F and Modbus RTU protocols, enabling seamless integration into industrial automation networks for remote monitoring and data acquisition.

The device accepts a supply voltage of 100 to 240 VAC and is compatible with a wide range of external current transformers (CTs) with primary ratings from 5 A up to 600 A, providing flexibility for different load capacities. The module includes pulse output capability for integration with external totalizers or PLC counters, making it suitable for energy management and cost allocation applications.

Technical Specifications

Key Features

• Pulse output facilitates connection to external counters, totalizers, or PLC high-speed counter inputs for energy accumulation.

• Compatible with external current transformers from 5 A to 600 A primary ratings for flexible installation across different load capacities.

• Multiple CT options including KM-NCT-5A/50A, KM-NCT-100A, KM-NCT-225A, KM-NCT-400A, and KM-NCT-600A.

• Comprehensive electrical measurements including voltage, current, active power, and cumulative energy.

• Up to four measurement circuits can be monitored within a single KM-N1-FLK unit, each operating independently.

Applications

The Omron KM-N1-FLK small power monitor is deployed in industrial and commercial facilities requiring energy monitoring and management. In manufacturing environments, the device monitors individual machine power consumption for efficiency analysis and predictive maintenance. In facility management applications, it tracks lighting circuits, HVAC equipment, and miscellaneous loads for energy cost allocation.

Common applications include production line energy monitoring, machine-level power measurement for efficiency improvement programs, sub-metering for tenant billing, and data collection for ISO 50001 energy management systems. The KM-N1-FLK is typically installed within control panels, with CTs clamped around conductor wires to measure current without interrupting circuit operation.
