The QNHCK2-16 Hall Effect Current Transducer is a precision split-core current sensor designed for accurate measurement of DC currents ranging from ±20A to ±150A. This versatile sensor features a convenient clamp design that allows for easy installation around existing conductors without the need to disconnect or break the circuit, making it ideal for retrofitting and maintenance applications. Operating on a +5V supply, the transducer delivers a proportional 2.5V output signal with variations of ±0.625V to ±2V depending on the measured current, providing reliable analog feedback for monitoring and control systems. With an impressive bandwidth spanning from DC to 25KHz, this sensor captures both steady-state and rapidly changing current signals with precision. The device offers galvanic isolation up to 2.5KV, ensuring safe operation by electrically separating the measurement circuit from the monitored high-current line. Built to withstand demanding environments, it operates reliably in temperatures from -10 to +70°C and can be stored in conditions ranging from -25 to +70°C. This current sensor meets international quality standards with CE, RoHS, and UL certifications, making it suitable for industrial automation, power management systems, motor control applications, and energy monitoring solutions.
