1. Electronics Components - Technology and Materials The transducer is the term used collectively for Actuator and Sensors which is used to sense a different type of energy such as radiant energy, movement, an electrical signal, thermal energy and magnetic energy. The Actuators is used for switching between currents and voltages. For a person to on electric circuits, the sensors and transducers have analog and digital with input and output to choose. The most important factor depends on the type of signal the sensor used. Once the process of sensed or controlled is defined between the sensor and transducer is made, the energy converts from on physical quantity in another. Today, there is a different type of sensors and sensor easily available in the market place. The most common sensors are the CT 0.4-P, CTSR 0.3-P and FHS 40-P/SP600 which are used to measure and controlled the quantity. But, the most preferred on are CKSR 25-NP and CKSR 50-NP Transducer. A CKSR 50-NP is a multi-range current transducer which has a closed loop covered in an isolated plastic case construction for sager use. The CKSR series has CKSR 25-NP and CKSR 50-NP Transducer which works as an electronic measurement of current DC, AC. This works as a galvanic isolation between the primary and the secondary circuit. The common use of CKSR series in battery supplies, switched mode power supplies, uninterruptible power supplies, static converters for DC motor drives and providing the power in welding and solar inverter. The main features of CKSR 50-NP transducer are as follows: There is always a single supply of power It has a compact design for PCB mounting Very low-temperature coefficient of offset Excellent DV/dt immunity Superior creep age/clearance distances Condensed height With UL94V-0 Flammability rating With the correct knowledge of transducer and Sensor, we can make the power supply easy without having any short circuit between two objects.
