Current Sensors Compact, reliable sensors for measuring AC and DC current in industrial, commercial, and laboratory systems. Designed to provide accurate current information while maintaining electrical isolation and minimal impact on the measured circuit. Key benefits Accurate measurement: Delivers consistent current sensing for monitoring, control, and protection tasks, helping systems respond correctly to load changes or fault conditions. Electrical isolation: Provides galvanic isolation between the measured circuit and the downstream electronics, improving safety and reducing interference risk. Versatile mounting and sizing: Available in throughhole, PCB mount, clampon, splitcore, and panel configurations to fit tight spaces or retrofit existing installations. Wide range coverage: Suitable for lowlevel milliamps up to several hundred amps, enabling use across small electronics, motor drives, and power distribution panels. Low insertion loss and wide bandwidth: Designed to minimize disturbance to the monitored circuit while accurately capturing steadystate and dynamic currents. Durable construction: Housings and components selected for longterm performance in industrial and commercial environments. What it does and why you need it Converts current into a measurable electrical signal that can be read by controllers, data loggers, meters, and protection relays. Enables realtime monitoring and closedloop control for energy management, motor and inverter control, battery systems, and safety trip circuits.
