• M83530/1-2000B application field and working principle

  M83530/1-2000B is a radial leaded metal oxide varistor (MOV) from M83530 Series. It has passing voltage rating of 800V and transient current rating of up to 2000A. The diameter of this varistor is 13mm. It is suitable for protecting low voltage circuits. The working principle of this MOV is very simple. It is just an electrical device which can be used to protect against high voltage surges. When the current through this component exceeds its rated value, it will change its resistance so as to divert the excess current away from the circuit.

• Applications of M83530/1-2000B

  M83530/1-2000B can be used for various applications such as telecommunications, consumer electronics, industrial, computer and audio/visual equipment. It can be used for transient voltage suppression, power line noise suppression, lightning protection and other low voltage protection applications. For example, it can be used to protect cell phone chargers, compact disc players, car audio systems, etc.

• Construction of M83530/1-2000B

  M83530/1-2000B is made up of a zinc oxide (ZnO) material. This material is a non-linear, non-polarizing, capacitive-type resistor which can respond to transient pulses faster than other protection components. It has a high storage capacity and low leakage current characteristics. It has a body consisting of a hollow cylindrical form. It has two leads or pins which are placed on either side of the varistor so that it can be easily inserted into a circuit board. The internal resistance of the MOV is in the range of 23 ohms to 500 ohms.

• Advantages of M83530/1-2000B

  M83530/1-2000B has many advantages over other components in this category. It has a high surge capability and can dissipate high levels of energy during transient surges. It is easy to install and does not require complicated wiring. It provides superior protection against high transient pulse riding on the power supply line. It is also very cost effective compared to other components of this type.

• Disadvantages of M83530/1-2000B

  M83530/1-2000B has some drawbacks too. It has limited capability to suppress high frequencies signals. It is relatively slow in responding to sudden increase in voltage or current. Also, its internal resistance is not constant which can lead to inaccurate protection. Lastly, due to its small size, it may not be able to respond to large surges of current.

• Conclusion

  M83530/1-2000B is a radial leaded metal oxide varistor which can provide very low cost protection against high transient pulses on the power line. It is suitable for use in telecommunications, consumer electronics, industrial, computer and audio/visual equipment. It is easy to install and provides superior protection though it has some drawbacks. It is important to select the right MOV based on the requirements of the circuit to ensure proper protection.
