The QNHCK2-16 split core current sensor is an essential tool for professionals who need accurate current measurement without disrupting existing electrical systems. This hall effect current transducer features an innovative split core design that opens like a clamp, allowing you to install it around conductors without disconnecting wires or shutting down equipment. With a rated capacity of 20A and output of 2.5V±2V, this sensor delivers precise measurements for both AC and DC current applications. The device operates on a +5V supply and offers an impressive bandwidth of DC to 25KHz, making it ideal for monitoring dynamic current changes in real-time. Its compact construction includes galvanic isolation rated at 2.5KV, ensuring safe operation and protecting your measurement equipment. The color-coded output wires (red, yellow, black, and blue) simplify integration into your monitoring or control system. Operating reliably in temperatures from -10 to +70°F, this current transformer is suitable for industrial automation, power monitoring, motor control, and energy management applications. The sensor's hall effect technology provides non-contact measurement, eliminating insertion losses while maintaining accuracy across its full measurement range.
