NK ASC-NOU-5-SP-sss - Current Operated Switches, Normally Open, 50 Hz, 003 to 150 Split Core

ASC Series

• Current Operated Switches
• 50hz, Primary Circuit Frequency
• Output Rating: Normally Open
• Case Style: Split-Core
• Factory Set Trip Point: 003 to 150 Split-core

ASC Series Current Operated 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.
