The PMI TLAR-S Compact Current Clamp is a high-precision current probe engineered for accurate power quality measurements in space-constrained environments. Designed with a compact form factor, it enables reliable current measurement in tight electrical enclosures where standard clamps may not fit, without compromising measurement performance.

With selectable 20A and 200A ranges, the TLAR-S delivers strong resolution at low current levels while maintaining the capability to measure higher loads. Its wide frequency response from 40 Hz to 10 kHz ensures accurate capture of both fundamental current and harmonic content, supporting detailed waveform analysis and diagnostics.

Optimized for use with PMI power quality recorders, the TLAR-S integrates seamlessly into monitoring systems for waveform capture, harmonic analysis, and event detection. Its robust construction and 600 VAC CAT III safety rating allow safe operation in demanding industrial and utility environments.

By combining compact design, measurement accuracy, and dependable performance, the TLAR-S enables precise current monitoring where space limitations would otherwise restrict data collection.

Features & Benefits

The TLAR-S Compact Current Clamp is designed to provide accurate current measurement in applications where space is limited and installation flexibility is critical. Its compact probe design allows it to be installed in tight electrical panels, crowded enclosures, and other constrained environments without sacrificing measurement quality. This makes it particularly valuable for field technicians and engineers working in real-world conditions where access is restricted.

With dual 20A and 200A ranges, the clamp offers flexibility across a wide range of applications while maintaining strong resolution at lower current levels. This enables more precise measurement of subtle load variations and improves the overall accuracy of power quality analysis. The wide frequency response from 40 Hz to 10 kHz supports accurate measurement of both fundamental current and higher-order harmonics, allowing users to diagnose distortion and waveform-related issues more effectively.

Measurement consistency is enhanced by low sensitivity to conductor positioning and nearby conductors, helping ensure reliable data even in dense electrical environments. The clamp’s phase shift characteristics further support accurate analysis across varying current levels.

Rated for 600 VAC CAT III environments, the TLAR-S is suitable for industrial and utility applications where safety is essential. Its compatibility with PMI recorders allows seamless integration into existing workflows, enabling high-quality waveform capture, harmonic analysis, and long-term monitoring in even the most space-restricted installations.
