CR4160-15

Current Sensors Overview

The CR4160-15 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a dual-element split-core design with a 0.26-inch window and supports an input range of 0.5 to 30 AAC. The device provides a 4mA to 20mA output signal with ±0.5% accuracy across a 20Hz to 5kHz frequency range. Powered by 24V DC with a maximum current draw of 70mA, it offers a 250ms response time. Mounting options include 35mm DIN rail or panel installation, operating within a temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• True RMS measurement capability ensures high precision for chopped wave and phase-fired control systems
• Dual-element split-core construction allows for easy installation without disconnecting primary conductors
• Regulatory compliance with UL 61010B-1 and CAN/CSA-C22.2 standards for industrial safety

Current Sensors Applications

• Phase-fired controlled heaters
• Quickly varying motor loads
• Chopped waveform drivers

Current Sensors Procurement Notes

Verify that the specific part number CR4160-15 corresponds to the 4mA to 20mA output variant, as the CR4160 series may offer different output configurations. Confirm the required input range matches the 0.5 to 30 AAC specification for your application. Ensure the power supply meets the 24V DC requirement with sufficient current capacity exceeding 70mA. Check for any specific mounting hardware requirements for DIN rail or panel installation if not included in the standard package.

Current Sensors Selection Notes

Select this model when accurate measurement of distorted AC currents is critical, such as in phase-controlled heating applications. The split-core design is suitable for retrofits where breaking the circuit is impractical. Choose the 4-20mA output version if interfacing with PLCs or industrial controllers requiring current loop signals. Consider the 20Hz to 5kHz frequency range to ensure compatibility with the system's operational bandwidth.

Current Sensors Part Context

This component belongs to the CR4100 Series of True RMS Current Transducers manufactured by CR Magnetics. The series includes single, two, and three-element variants with various input ranges and output options. The CR4160 specifically denotes a two-element split-core unit, distinguishing it from the single-element CR4110/CR4120 and three-element CR4170/CR4180 models.
