TVS - Varistors, MOVs are metal oxide varistors (MOVs) that have been widely used for surge protection, power quality and lightning protection. V150ZS20PX2855 is one of the most common type of MOVs used in the field.

The V150ZS20PX2855 is a two-wire, self-protected varistor, designed to protect against transient voltage surges and other voltage-related events. It is particularly useful in applications that have high capacitance, such as motor drives, on-site power distributions and switchgear. Its protective capability is provided by its ability to discharge a high amount of current at a given voltage.

The V150ZS20PX2855 has two primary operating modes: the clamping mode and the dissipation mode. In the clamping mode, the varistor will clamp the voltage of the line to a predetermined level. This is the mode in which it is most commonly used to protect against surges. In the dissipation mode, the varistor will draw current from the circuit, resulting in the dissipation of energy.

The working principle of the V150ZS20PX2855 is based on the capacitive nature of the device. When the voltage across the device exceeds a certain level, the capacitive property is triggered, and current is drawn from the circuit and dissipated. This happens instantaneously and the device acts as a filter or circuit breaker, protecting the circuit from damage.

The V150ZS20PX2855 is typically used in applications where overvoltages occur, such as motor drives, on-site power distributions, and switchgear. In these applications, they can be used to protect against surges and lightning strikes, as well as for EMC (electromagnetic compatibility) compliance. The protection provided by the V150ZS20PX2855 is essential for keeping the equipment protected and ensuring the reliability of the system.

When used in surge suppression applications, the V150ZS20PX2855 protection is specified as a single pulse event (SPE) rating. This rating indicates the maximum voltage and surge current which the protection device can handle, without being damaged. The SPE rating also indicates the peak clamping voltage and the peak pulse current at which the protection device will be able to discharge the surge current without allowing any damage to the connected equipment.

In lightning protection applications, the V150ZS20PX2855 varistor is typically installed between the mains supply and the protected equipment. This will help to protect the equipment from surges or lightning strikes. The V150ZS20PX2855 has a fast response time and is able to discharge high amounts of surge current. This ensures the equipment is protected from damage.

In terms of EMC compliance, the V150ZS20PX2855 varistor helps to protect the system from electromagnetic disturbances. This is done by absorbing the transient voltage pulses that are emitted by other equipment or from the environment, such as induction motors, lighting strikes, and electrostatic discharge.

The V150ZS20PX2855 is a robust transient voltage surge protector with a variety of applications. It has been widely used in various applications, such as power quality, surge protection, and lightning protection, for many years. This device is able to absorb a considerable amount of energy and provide excellent protection for a variety of different systems.
