Description

The J&D JM21NH series of Split-core current transducers provide a proportional output based on the source current

  • They offer galvanic isolation between the primary circuit (power) and the secondary circuit (measurement)
  • Designed for energy management with a convenient connection to most sub-meters
  • Compatible with current measurement systems connected to power line carriers (PLCs) or remote controlled software systems such as SCADA when used for automation
  • Can be used for security applications, condition monitoring, load monitoring, protection systems and for predictive maintenance of conveyors, pumps and HVAC motors
  • The split-core design allows for easy installation in existing architecture
  • MAIN CHARACTERISTICS
    • Current transformer and RMS circuit in a single case
    • Choice of primary current ranges: 5 to 250A (model dependent)
    • Available Outputs:
      • 0-5 Vdc (V)
      • 4-20mA (RMS)
    • 4-20mA DC output is proportional to the RMS value of the primary current
    • Accuracy: <2% of nominal primary current
    • Bandwidth: 50/60 Hz
  • APPLICATIONS
    • Automation and supervision
    • Safety and condition monitoring
    • HVAC & pumps
    • Refrigeration
    • Small industrial motors
    • Fans
    • Lighting
  • FEATURES
    • True-RMS (Bipolar DC in => Unipolar DC out)
    • Active 0-5 Vdc output proportional to the RMS value of the primary current
    • Single power supply (24 Vdc)
    • Operating range: -20°C to +60°C
    • Isolation test voltage : 3.5kV RMS / 50Hz / 1min
    • Sensing aperture : 21mm
    • UL94-V0 recognized materials
  • BENEFITS
    • High isolation between primary and secondary circuits
    • Compact case
    • Cost-effective solution
    • Easy installation
