Current Sensors Procurement Notes

Verify that the specific part number matches the required primary current rating of 200A and the 4-20 mA output configuration. Confirm compatibility with the intended 12-24 Vdc supply voltage and operating temperature environment. Ensure the split core aperture size accommodates the target conductor dimensions for proper magnetic coupling and measurement accuracy.

Current Sensors Selection Notes

Select this model when high current capacity up to 200A is required for AC measurements. The split core design is advantageous for retrofitting existing installations where breaking the primary circuit is not feasible. Consider the 150ms response time for dynamic load monitoring applications. Verify that the DIN rail or panel mounting options fit the available enclosure space and mechanical constraints.
