The QNDBK2-16 is a split core current transmitter designed for accurate and reliable AC current measurement across a wide input range, from 1A up to 500A, with a standardized DC 4-20mA output signal. Its split core clamp design allows for quick and convenient installation directly onto existing wires without the need to disconnect or interrupt any circuits, saving time and effort during setup. With a high accuracy rating of 0.5% and linearity of 0.2%, this current transformer sensor delivers consistent and dependable readings suitable for demanding industrial and commercial applications. Built-in galvanic isolation up to 3kV AC provides an added layer of protection against electrical surges. The unit operates on a +24V supply voltage and functions reliably across a wide temperature range of -4°F to +158°F (-20°C to +70°C), making it well-suited for challenging environments. The compact, rugged black housing features clearly labeled OUT and PWR terminals for straightforward wiring. Single-phase operation and compatibility with standard 4-20mA signal inputs make integration into existing monitoring and control systems straightforward.
