Current Sensors datasheet and documents for AS3-NODC-SP
Current Sensors Overview
The AS3-NODC-SP is a split-core AC current switch manufactured by NK Technologies. It features an adjustable setpoint range of 1.5 to 150 Amps and utilizes top terminals for electrical connections. The device is powered by 24 VAC/VDC and includes SmartLED status indication. Designed for through-hole installation, it provides reliable circuit monitoring with field-adjustable sensitivity within the specified current range.
Current Sensors Feature Summary
- Split-core design allows for non-intrusive installation around existing conductors
- Field-adjustable setpoint enables precise calibration for specific load requirements
- Integrated SmartLED provides visual status indication for operational monitoring
- Top terminal configuration facilitates convenient wiring access
Current Sensors Applications
- Industrial motor protection circuits
- HVAC system current monitoring
- Electrical panel load management
- Automated machinery safety interlocks
Current Sensors Procurement Notes
Verify that the required setpoint range falls within the 1.5 to 150 Amp specification. Confirm compatibility with the 24 VAC/VDC power supply in the target environment. Ensure the split-core aperture matches the diameter of the conductor being monitored. Check for necessary mounting hardware and terminal block accessories if not included in the standard package.
Current Sensors Selection Notes
Select this model when a split-core solution is preferred over solid-core alternatives for retrofitting or complex wiring scenarios. The adjustable setpoint offers flexibility compared to fixed-setpoint variants. Consider the SmartLED feature if visual diagnostics are required without additional instrumentation. Verify that the top-terminal orientation fits within the available enclosure space.
Current Sensors Part Context
This component belongs to the AS3 Series of AC current switches from NK Technologies. The series includes both solid-core and split-core options with various terminal configurations. The AS3-NODC-SP specifically addresses applications requiring high-current monitoring up to 150 Amps with flexible installation capabilities.
Current Sensors Replacement Considerations
Direct substitutes include other NK Technologies AS3 series split-core models such as AS1-NOU-SP or AS1-NCU-SP, provided they meet the voltage and current specifications. Cross-reference terminal types and LED features to ensure functional equivalence in the existing assembly.
