PQube®3 CTI-5A Module Ultra-accurate way to measure currents from 5-amp CT secondaries Connect 5-amp CT's (Current Transformers) to your PQube®3 Connect your 5-amp output CT's (e.g. 1000:5, 100:5, etc.) to your PQube®3 (or PQube®3e). The CTI-5A module is an ultra-accurate interface to metering and/or protection CT's. Each CTI-5A module connects up to four 5-amp circuits. Use as many CTI-5A modules as you need; the only limitation is the number of current channels on your PQube®3. Your PQube®3 automatically calculates all of its current and power values - just type your CT ratio into your PQube®3's Setup.ini file, and your PQube®3 will do the rest. And every CTI-5A module comes with an individual Calibration File and NIST-trace Certificate, guaranteeing laboratory-grade accuracy! • Ultra-accurate - fully certified to IEC 62053-22 Class 0,2S and ANSI C12.20 Class 0.2 revenue accuracy, IEC 61000-4-7 Class I harmonic accuracy - and unlike most other instruments, this certification includes both your PQube®3 accuracy and your CTI-5A accuracy, combined! • Ultra-safe - the 5-amp withstand capability is 250 amps for 1 second without damage. • Ultra-compatible - less than 0.1 VA burden on your CT, easily compatible with existing instrument/meter/protection transformers. • Ultra-convenient - DIN-rail mounting, no power required - you can install CTI-5A at a distance up to 5 meters from your PQube 3. • Ultra-harmonic accuracy - fully certified to IEC 61000-4-7 Class A harmonic current requirements! IEC 62053-22 Certified Influence Quantities: Load, Power Factor, Voltage, Ambient Temperature, Frequency, Phase Sequence, Harmonics, Subharmonics, AC magnetic field, DC magnetic field, RF fields, Conducted RF. Order Information • PSL model number CTI-5A-XX • Each CTI-5A module can connect one, two, three, or four 5-amp CT circuits to your PQube®3. • Your CTI-5A comes with a 12" / 30cm shielded cable for connection to your PQube®3 current channel screw terminals. (contact the factory if your application requires a longer cable.)
