Product Description
High Sensitivity Flexible Rogowski Coil for Advanced AC Current Measurement
Discover our High Sensitivity Flexible Rogowski Coil (SRC Series), an advanced flexible current transducer for precise AC current measurement from 1A to 500kA. Features high linearity, wide bandwidth, and safe operation. Ideal for power monitoring, harmonics analysis, and DC ripple measurement.
Key Features & Benefits
- High Precision & Wide Dynamic Range: Achieve accurate AC current measurement from 1A to 100kA (up to 500kA max) with excellent linearity of ±0.2%. The calibrated version offers a remarkable accuracy of <0.5%.
- Ultra-Flexible & Non-Intrusive: Our flexible current transducer easily wraps around large, awkward, or fixed conductors (bus-bars, cables) in confined spaces. Its 12mm slim coil section and lightweight design make installation simple with cable ties.
- Inherently Safe & Robust: Unlike traditional CTs, there is no danger from an open-circuited secondary. It does not saturate, even with massive overcurrents or short circuits. Rated for CAT III 1000V / CAT IV 600V and designed for demanding environments.
- Broadband Performance: With a wide bandwidth of 1Hz to 100kHz (-3dB), it is perfect for analyzing harmonics, transients, and DC ripple measurement in applications like battery charging systems.
- Integrated Shielding: An internal shield ensures stable measurements by rejecting interference from external magnetic fields, enhancing accuracy even at low primary currents.
- Plug-and-Play Compatibility: This Rogowski coil can be directly connected to our DIN-RAIL and panel meters without an external Rogowski coil integrator, simplifying your system setup.
