V460LT20CP

TVS (transient voltage suppressors) devices, MOVs (metal oxide varistors) and other varistors are becoming increasingly commonplace, as their effectiveness in controlling transient voltages has been demonstrated in a number of successful applications. One such device is the V460LT20CP, a varistor specifically designed for appliance and LED lighting applications. In this article, we will look at the application field and working principle of the V460LT20CP.

The V460LT20CP is an axial-leaded, thermally enhanced surge protector for AC/DC applications. It is designed specifically for outdoor LED lighting applications, and features a working voltage up to 460V AC/DC, as well as a very low clamping voltage. The device is also RoHS compliant, and has a maximum capacitance of 800pF. It has an extremely low typical on-state resistance of 0.093 ohms, and a maximum current of 20A. In addition, it has a reliable maximum surge response time of 10µs, ensuring that it can absorb transients quickly and effectively.

The V460LT20CP is primarily used in AC/DC applications, and can be used for a variety of different purposes. It is widely used in outdoor LED lighting applications, as it can help protect these lights from transients and other surges. In addition, it can be used in smart grid/utility applications, as it can help reduce the effects of lightning or other power disturbances on sensitive components. The device is also well-suited for large AC motors, as it can help to reduce the effects of overvoltage and other voltage spikes on the motors.

The working principle of the V460LT20CP is based on the principle of the metal-oxide varistor (MOV). An MOV is a type of voltage-dependent resistor that acts like a voltage-dependent capacitor, with a resistance that decreases as the voltage increases. This means that the V460LT20CP can effectively reduce the voltage of incoming transients by shunting them to ground. The device is constructed using a stack of MOV elements, which are connected in series to form a single, unified device. When the device is exposed to an overvoltage, it will effectively dissipate the excess energy into the surrounding environment or into the load itself, thus protecting the connected components from damage.

In conclusion, the V460LT20CP is an effective and reliable surge protection device for AC/DC applications, designed specifically for LED lighting and large AC motors. Its low on-state resistance and fast response time make it ideal for protecting sensitive components from transient voltages. The device operates on the principle of a metal-oxide varistor, and is able to effectively reduce the voltage of incoming transients to protect the connected components.
