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:
- 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
