Description

Multifunction Measurement Device DIN Rail 2×3-Phase RS485

Hager JKM02

The Hager JKM02 Multifunction Measurement Device is a versatile DIN rail-mounted energy monitoring solution for two independent three-phase systems or up to six single-phase circuits. Featuring RS485 communication, dual pulse outputs, and CT/VT compatibility, it is designed for advanced energy management in industrial and commercial environments.

Key Features of Hager JKM02 Multifunction Measurement Device

• Dual System Monitoring: Supports two independent three-phase (2x 3P+N) systems or six single-phase (6x 1P+N) circuits, ideal for multi-load monitoring.
• Wide Voltage Input Range: Rated for 60-300V AC (L-N) and 104-520V AC (L-L).
• RS485 Communication: Allows seamless integration into advanced energy management systems for real-time monitoring.
• Current Transformer (CT) Compatibility: Handles CT primary inputs from 5A to 10,000A with a 330mV secondary input.
• Voltage Transformer (VT) Compatibility: Supports VT primary inputs from 100V to 10kV and secondary inputs between 100-500V AC (L-L).
• Dual Pulse Output: Separate outputs for each monitored system, configurable from 5-27V DC with a maximum current of 100mA.
  • Pulse Mapping:
    • 3 Phase 4 Wire (2×3 Phase): ⎍1 = CT1 / ⎍2 = CT2
    • 1 Phase 2 Wire (6×1 Phase): ⎍1 = CH1+CH2+CH3 (CT1), ⎍2 = CH4+CH5+CH6 (CT2)
• Self-Supplied Auxiliary Power: Powered directly from L1 phase, simplifying installation.
• Compact DIN Rail Design: Efficient form factor for easy panel integration.
• Energy Efficiency: Low voltage rated burden of <8VA on L1 and <0.2VA on L2 and L3.
