Metal oxide Varistors ( MOVs or VDRs ) are voltage dependent resistors with symmetrical voltage-current characteristics which are designed to protect all kinds of electronic devices or elements from switching pulse or induced lightening surges. Its non linear characteristic with broad application range, mass production feasibility are gradually being used in various level of electric and electronic device from low to high voltages level protections ( AC11V- 1000 V as available ranges ).

（1）JOYIN Metal Oxide Varistor  JVR Standard Surge N series

Operating Temperature -40°C~ 85°C

The normal type N series of Metal Oxide Varistor are radial lead varistors (MOVs or VDRs) that are designed to be used continuously across AC line primary or DC circuit for transient voltage and surge suppression. 

For safety reason, UL , CSA , VDE , CQC certificate are a must before applied to end products.

（2）JOYIN Metal Oxide Varistor  JVR High Surge S series

Operating Temperature -40°C~ 85°C

The high surge current JVR S series are specific designed for high transient surge suppression. They are radial lead varistors (MOVs or VDRs) used continuously across AC line primary or DC circuit.

For safety reason, UL , CSA , VDE , CQC certificate are a must before applied to end products.

（3）JOYIN Metal Oxide Varistor  JVR Ultra Surge U series

Operating Temperature -40°C~ 85°C

The Ultra high surge current JVR U series are specifically designed for Ultra high transient surge suppression. They are radial lead varistors (MOVs or VDRs) designed to be the continuously used across AC line primary or DC circuit.

For safety reason, UL , CSA , VDE , CQC certificate are a must before applied to end products.
