What should you pay attention to during the use of Panasonic adjustable resistors? Many irregular operations and improper use methods will unreasonably reduce the service life of adjustable resistors, so we should look at some related before use. Content analysis and specific considerations.
What should you pay attention to during the use of Panasonic adjustable resistors? Many irregular operations and improper use methods will unreasonably reduce the service life of adjustable resistors, so we should look at some related before use. Content analysis and specific considerations.
1. We should strictly check the quality of the adjustable resistor before use. The shank of the Panasonic adjustable resistor should be flexible, no mechanical noise, and suitable for tightness. A multimeter is required to check the nominal resistance value, which should meet the requirements. If the multimeter measures the resistance between the fixed end of the adjustable resistor and the lug of the sliding end, the needle should be free from jumping and smooth rotation when the adjustable handle is slowly rotated.
2. The Panasonic adjustable resistor must be firm and reliable during installation. The nut to be tightened should be tightened in place with sufficient torque to prevent looseness and misalignment during use, and the circuit may be faulty if it collides with other components.
3. Panasonic adjustable resistors should not be used under overload and need to be used within the rated value. When the adjustable resistor is used as a varistor to regulate the current, the allowable power consumption should be reduced in proportion to the stroke of the movable contact contact brush. To ensure that the current flowing does not exceed the allowable rating of the adjustable resistor, the adjustable resistor is prevented. Local overload and failure. In order to prevent the current of the adjustable resistance from being close to zero, the current exceeds the maximum allowable value. It is better to connect a current limiting resistor in series to avoid damage caused by overcurrent of the adjustable resistor.
4. Various fine-tuning adjustable resistors can be directly mounted on the printed circuit board, but attention should be paid to the arrangement of adjacent components to ensure that the adjustable resistors are easily adjusted without affecting other adjacent components.
5. Since some parts of the adjustable resistor are made of synthetic resin such as polycarbonate, do not contain a large concentration of chemicals such as amines, ammonia, alkali solutions, aromatic hydrocarbons, halogenated hydrocarbons, and ketones. The application of the environment can extend the service life of the adjustable resistor.
6. When the adjustable resistance is seriously damaged, it is necessary to replace the new adjustable resistor. At this time, it is better to use the same adjustable resistance as the original adjustable resistance. It should also be noted that the axial length and the axial end shape of the adjustable resistor should be The original knobs match. If you can't find the original type, the original resistance of the adjustable resistor, you can replace it with a similar resistance and type of adjustable resistor. The rated power of the replacement adjustable resistor is generally not less than the rated power of the original adjustable resistor. In addition, the replacement of the adjustable resistor should also meet the needs of the circuit and use.
7. Unsealed adjustable resistors are most prone to noise-intensive faults, mainly due to oil and wear. At this time, it is absolutely impossible to solve the problem by applying a lubricating oil method. The lubricating oil will increase the accumulation of internal dust and conductive particles. The correct way to do this is to gently wipe the dirt on the resistor with a cotton ball dipped in absolute alcohol and remove the oil from the contact brush and the reed.
Through the above content review and reading, we have more or less understanding of the use of Panasonic adjustable resistors and precautions, the correct use of adjustable resistors can extend their life, so in order to better protect the use of adjustable resistors Please check the relevant precautions in time to lay a solid foundation for better product quality in the future. The quality of Panasonic adjustable resistors produced by Shenzhen Best is guaranteed. I hope that you will come to call us.
