At present, it has developed into a large protecting parts manufacturer which specialized on both developing and producing all series metal oxide varistor, SPD surge protector and lighting protection products. It became a leader in the same field.
The main voltage sense components are: MYG general varistor, MYL lighting protection varistor, MYE high load varistor, MYP silver element of high energy varistor, TMOV and various lighting protector fixture with independent intellectual property rights.
Metal Oxide Varistor
FAQ
-
Q: How do you determine correct size varistor on a 24vac coil?
A: You want the varistor to be several volts greater than the peak voltage of the signal across which it is connected.
-
Q: What Are the Functions of Varistor?
A: Varistors are voltage-controlled resistors. They are common in outlet strips, Uninterruptible Power Supplies (UPS) and on electrical power lines.

Electrical events, such as lightning, can couple into metallic conductors and cause damage from the excessive system voltages and currents (surges) generated. Surge protective devices (SPD) are used to mitigate these coupled surges in both High Voltage (HV) and Low Voltage (LV) power systems and communication systems. An Surge protective device has a non-linear voltage-current characteristic that reduces voltages exceeding the normal safe system levels by a rapid increase in conducted current. Kestar produces various surge protective device. Warmly welcome you to contact us.
