Key Features:
Wide Current Range: Available from 0-100A to 0-50,000A peak, covering a broad spectrum of current monitoring needs.
True RMS Output: Provides a DC output proportional to the true RMS of the primary current, ensuring accurate measurements even with harmonically distorted waveforms.
Fast and Easy Installation: Flexible, clip-on sensing coil allows for quick installation in applications with limited space. The split-core design makes installation possible without shutting down the electrical supply, avoiding expensive downtime costs.
Standard Output Options: 0-5V or 4-20mA DC output for easy integration with SCADA systems, PLCs, data loggers, and protection equipment.
No Magnetic Saturation: Ensures reliable measurement without signal degradation, even in demanding applications.
Intrinsically Safe Design: Suitable for environments where safety and reliability are critical.
Flexible Coil Lengths: Available in standard lengths of 300mm, 500mm, and 700mm; optional mini coils with 3.5mm thickness available in 100mm, 200mm, and 300mm lengths.
High Insulation Voltage: Rated for 2kV continuous insulation (tested to 4kV) with optional 10kV insulation (tested to 15kV).
High Accuracy: Ensures <1% accuracy over 5%-150% of the current range, with operation up to 150% FS 10.6V peak.
Applications:
The RCTrms is perfect for energy monitoring and current measurement in a variety of applications such as:
Factories
