Key Features of the CTSHL Series

• Direct PC-bus DAQ for IEC 61000-4-7 compliant sampling and high-speed streaming to disk for audit-quality records.
• PC-based Harmonic and Flicker test software with real-time color displays and continuous PASS/FAIL monitoring.
• Automatic calculation of maximum permissible system impedance (Zsys) using Zref and measured flicker parameters per EN/IEC 61000-3-11.
• Intuitive test setup, data analysis and reporting with export to PDF and MS Word formats.
• High-resolution, gapless acquisition for replay and detailed post-test analysis (ASCII export available).
• Single-step and fast playback modes for reviewing test results.

AC Power Source
The CTSHL configuration requires a Sequoia or Tahoe Series AC/DC source. These AC sources provide high current capability (up to 125 ARMS per phase) and advanced arbitrary waveform generation, precision measurements and waveform analysis. CTSHL is supplied as a configuration/option for these AC sources.

High-Speed Direct PC Data Acquisition
DSP-based data acquisition provides IEC-compliant sampling and direct PC-bus streaming. A signal conditioning and isolation unit (PACS-3-75) interfaces the AC source to the equipment under test (EUT), providing isolation, conditioning and anti-alias filtering. The EUT connects via a rear-panel terminal block.

Comprehensive Harmonics Analyzer
Includes an IEC-compliant power analyzer for detailed voltage and current measurements. Harmonics and inter-harmonics are measured continuously with no gaps to meet IEC 61000-4-7; monitoring includes pass/fail detection against IEC class limits with results stored in a password-protected database.

IEC-Compliant Flicker Reference Impedance
IEC 60725-compliant reference impedances are available: OMNI-3-75 (75 A RMS per phase) in a 43" cabinet for IEC 61000-3-11 and OMNI-3-37 for IEC 61000-3-3 (<16 ARMS). Quick-connect scheme allows switching between impedances.

Compliant Flicker Meter
An IEC 60868-compliant flicker meter (PACS) with DSP is integrated into the cabinet-mounted system.
