Installation Guidelines
-
Primary Conductor: Pass the conductor through the central aperture. For maximum accuracy, ensure the cable is centered and maintain a minimum distance of 5 mm from the sensor body for heat dissipation.
-
Magnetic Interference: Maintain a clearance of at least 25 mm (1 inch) from external magnetic components such as contactors or high-power transformers to prevent signal interference.
-
Mounting: The unit can be mounted in any orientation using the integrated screw holes.
-
Power Supply: Ensure the use of a regulated dual power supply (±15 V to ±18 Vdc). Unregulated supplies may result in measurement drift or potential sensor damage.
-
Connector: This model requires the Molex RSD-46607-001 mating harness for electrical connection.
FAQ
What is the primary function of the CSNK500M-600?
It provides electronic measurement of DC, AC, or pulsed currents with high precision and galvanic isolation, utilizing a feedback system to keep magnetic flux in the core at zero.
Can this sensor be used for high-speed switching applications?
Yes, its 1-microsecond response time makes it ideal for high-speed switching environments, such as those found in modern power converters and motor drives.
Is this sensor affected by the orientation of the primary conductor?
While the sensor can be mounted in any orientation, the primary conductor should be passed through the center of the aperture to maintain specified accuracy levels.
