MOV Varistors
Information of MOV Metal Oxide Varistor is referred MOV, usually closed to the edge of the PCBA design on the Layout side, especially will be at the main power source supply into or transmit port, the important is regulated the energy firstly when entering. MOV role is prevention of surge from lightning cable into the products lead to damage; Prevention unstable power voltage following the ON/OFF side access to the circuit, make the product function damage; Prevention damage static electricity into the product.
1. Recognize the maximum allowable voltage: (product working voltage /supply voltage ), power supply: AC or DC; 2. Pay attention to the stability of the supply voltage: ± 10%,±30% or±20%; 3. Maximum voltage (transient surge voltage of the device can accept); 4. Confirm Energy=K*Vc (v) *Ipp (a) *Time (s) 5. V1mA=1.5Vp=2.2Vac, the Vp is the peak of circuit rated voltage (1.414*Vac), Vac is a valid value of the rated AC voltage, selection the Vdr is essential, it is related to protection and longevity. |
