Features:
- Multi-Input Channels: Features 5 voltage inputs (up to 1000 VAC/DC) and 4 current inputs, all isolated, allowing for comprehensive monitoring of multi-phase systems.
- Wide Measurement Range:
- Voltage: 5 V to 1000 VAC and VDC.
- Current: TRMS current measurement (sensor dependent, e.g., up to 3000 A or 12000 A with appropriate flexible current sensors).
- Frequency: 42.50 Hz to 69.00 Hz.
- Intuitive User Interface: Large 7-inch color LCD touchscreen display (800 x 480 WVGA) for easy setup, real-time waveform viewing, and data analysis.
- Extensive Data Logging & Storage:
- Records over 900 parameters.
- Trend recording with programmable sampling periods (e.g., 200 ms for 3 days, 1s for 15 days, 3s for 45 days).
- 16 GB SD card for data storage (snapshots, transients, alarms, trends).
- No maximum for transient and inrush capture (limited by SD card space).
Capabilities:
- Advanced Power Quality Diagnostics:
- Harmonics & Interharmonics: Measures and displays harmonics up to the 127th order and interharmonics up to the 126th order (IEC 61000-4-7 compliant) for in-depth analysis of waveform distortion.
- True InRush®: Records RMS and peak inrush currents over extended periods (up to 30 minutes) to analyze motor startup and load behavior.
- Voltage Unbalance: Calculates voltage unbalance for assessing phase loading and system health.
- Power Factor (PF), Displacement Power Factor (DPF), Crest Factor (CF), Total Harmonic Distortion (THD).
- K Factor & FHL calculations.
- Carrier Current Detection.
