OMRON KM-N3-FLK Power Monitor

The OMRON KM-N3-FLK is a versatile and multi-circuit power monitor designed for on-panel installation. It offers comprehensive power measurement capabilities, making it an ideal solution for industrial automation applications. This device supports various phase wiring methods, including single-phase two-wire, single-phase three-wire, three-phase three-wire, and three-phase four-wire configurations.

Key Features:

• Multi-Circuit Measurement: The KM-N3-FLK can measure up to four circuits in single-phase two-wire configurations, two circuits in single-phase three-wire or three-phase three-wire setups, and one circuit in a three-phase four-wire system.
• Power Supply and Input: Operates with a power supply voltage of 100 to 240 VAC at 50/60 Hz. It can handle a wide range of input voltages, including single-phase 100 to 277 VAC and three-phase 173 to 480 VAC.
• Comprehensive Measurements: Measures total power consumption (active, regenerative, and reactive), power (active and reactive), current, voltage, power factor, and frequency.
• User Interface: Features an LCD display with intuitive operation buttons.
• Communication: Supports RS-485 communication with Modbus (RTU) and CompoWay/F protocols, allowing seamless integration into existing systems.

Technical Specifications:

• Accuracy: Offers high accuracy in active power measurement with a 0.5% error margin (IEC 62053-22 class 0.5S) and 2% for reactive power (IEC 62053-23 class 2).
• Sampling Cycle: 80 ms for 50 Hz and 66.7 ms for 60 Hz systems.
• Insulation and Dielectric Strength: Ensures safety with 20 MΩ insulation resistance and 1,400 VAC dielectric strength.
• Environmental Resistance: Designed to operate in temperatures from -25°C to 55°C and humidity levels between 25% and 85%.

Safety and Compatibility:

• Compliance Standards: Conforms to EN 61010-2-030, EN 61326-1, and UL 61010-1 standards.
• Environmental Conditions: Suitable for industrial electromagnetic environments (EN/IEC 61326-1 Table 2) and overvoltage category II.
