AC/DC Surge Protector - dealing with the voltage irregularities
Posted by surgeprotection on November 6th, 2018
A surge is an increase in the threshold level of voltage entering in any device. Every electrical system works on specific voltage level prescribed by the manufacturer. They are never designed to handle such giant voltage impulses. The power surges are a frequent event in every electrical circuitry. They occur due to lightning strikes, faulty or complex wiring, switching activities, etc.
A surge protector is a device that absorbs the voltage hike and clamps the voltage level to a permissible limit. Modern electrical and electronic devices have outthrown complex old technological designs but are crucial and delicate to handle. Surge protection devices are needed to maintain the continuous working of such systems. There are majorly two types of protection units – Primary Protectors and Secondary Protectors. Primary protection units are installed at the service entrance that protects all the devices connected after the entrance level. They work against the direct lightning strikes. Along with these, secondary surge protectors are also a must.
Protecting the AC power lines and DC power systems, the AC/DC SPDs deliver a lot more. They are a credit to protect system or devices from lightning and switching surges. The signaling and the telecommunications systems are majorly susceptible to these harmful events as these systems are highly complex and runs over a longer distance. They are also exposed to hostile environment at all times. Running from building to building crossing a larger distance, these twisted pairs and the equipments need to be balance and filtered from transient impulses. Thinking of the physical environment that the system is intended to stay, AC/DC surge suppressors are installed for robust protection applications. There are a several delicate equipments in the communication networks that needs to be protected. AC/DC Surge protection device are available in 230V, 110V, 48V, 24V and 12V. They are designed as per the requirements in each sector. For the protection of telecommunication system, a signal surge protection module is cascaded with the equipments. It complies with IEC 61643-21 which highlights its testing and installation procedure. It promptly responds to the voltage transient in less than 20ns and also offers an IP 20 degree of ingress protection. These Surge suppressors are designed with features such as low resistance units, high bandwidth and are also accessible for wider range of voltages.
