CTS 3-Phase Current Sensor Solution

The CTS 3-phase current sensor demo board enables accurate measurement of up to three independent AC currents, each up to 100A. A high-linearity laminated magnetic core, combined with Renesas metrology MCUs such as the RL78/I1C or RA2A2 and RAA788000 Rogowski effect current sensor, delivers precise analog measurements for standard 50/60Hz metering applications. With the optimized material and custom design, the solution achieves better than ±0.5% accuracy across the 0.1A to 100A range, meeting IEC, ANSI, and CENELEC requirements.
