The QNDBK2-16 split core current transmitter is a precision instrument designed for accurate AC current measurement and monitoring. Featuring a convenient clamp-on split core design, this current transformer sensor can be installed directly onto existing wiring without the need to disconnect any cables, making it ideal for retrofitting into existing electrical systems. It accepts a wide input range from AC 1A up to 500A and delivers a standard 4-20mA DC output signal, ensuring compatibility with a broad range of monitoring and control equipment. With an impressive accuracy rating of 0.5% and linearity of 0.2%, it provides reliable and consistent current readings. The built-in 3kV galvanic isolation enhances safety and minimizes electrical noise interference. Powered by a 24V DC supply, this single-phase transmitter operates reliably across temperatures ranging from -20°C to +70°C (-4°F to +158°F). Its compact, rugged construction makes it well-suited for industrial, commercial, and building automation applications where dependable current sensing is essential.
