NK ASC-NCU-5-SP-002 - Factory-Calibrated Current Operated Switch - 50Hz, Split-Core

ASC Series Current Sensing Switches are precision calibrated at the factory per customers’ specifications and guaranteed within 1% accuracy. Because the switch is factory calibrated eliminating the need to turn the potentiometer to the correct position in the field, installation time is substantially reduced resulting in a significant cost savings. The ASC combines a current transformer, signal conditioner and limit alarm into a single package for use in status monitoring or proof of operation applications and is perfect for OEM applications where the need for a limit alarm is required. Available in a solid-core or a split-core case to maximize ease of installation.

Current Sensing Switch Applications

• Electronic Proof of Flow
  • Current operated switches eliminate the need for multiple pipe or duct penetrations and are more reliable than electromechanical pressure or flow switches.
• Conveyors
  • Detects jams and overloads.
  • Interlocks multiple conveyor sections.
• Lighting Circuits
  • Easier to install and more accurate than photocells.
• Electrical Heaters
  • Faster response than temperature sensors.
