The VDRS07H300TLE is a high-performance Varistor, also known as Voltage Dependent Resistor (VDR). A Varistor is a non-linear device that reduces voltage peaks produced in industrial and/or residential applications. The VDRS07H300TLE Varistor is designed to protect AC circuits and DC circuits up to 300 VDC. When subjected to surges or transients, the VDR absorbs the excess voltage and standardizes the output load voltage to secure safe operation.

The VDRS07H300TLE is primarily used in residential and commercial settings or premises where a safety device is necessary to protect AC or DC circuits. The device can also be used for industrial applications that require surge protection or voltage transient protection. The Varistor works on the principle of variable resistance that varies as per the input voltage applied to it. This allows the VDR to reduce the transient energy generated and provide safeguard for the power lines.

In addition to the protection for AC or DC circuits, the VDRS07H300TLE also has excellent current-handling capabilities with high current density of 25 A at 8/20 us pulse duration. The device features a low dissipation factor of 7 watts and a low backward leakage of 0.5 uA, making it an ideal choice for high current applications. The Varistor supports a wide range of operating temperatures from -40°C to 85°C.

The VDRS07H300TLE is built in a shielded, non-vented, metal oxide housing and marketed as a UL1449 4th edition listed device. The device has been designed to meet the requirements of the IEC 60950-1,UL1449 4th Edition, UL1283, UL94 V0, and RoHS standards. The device has a high surge capability of up to 5kA (8/20µs). It is an above-average product designed to protect AC or DC circuits from transients up to 300 volts.

The working principle of the VDRS07H300TLE is to provide surge or transient protection for the power lines by reducing the impact of surges and transients. It acts as a voltage-dependent resistor by changing its resistance with the input voltage. The Varistor absorbs the energy from the surge and dissipates it effectively while providing a safe voltage for the connected equipment. The Varistor also works on the principle of current-limiting technology which allows it to safely and efficiently limit the flow of current to the protected devices.

The VDRS07H300TLE is a safe and reliable device designed to reduce voltage peaks and provide surge protection for residential or commercial applications. It operates on the principle of variable resistance and current-limiting technology and supports a wide range of operating temperatures. The device is designed to meet the requirements of various safety standards and has a high surge capability of up to 5kA (8/20µs).
