Surge Protection for Primary and Secondary Power Supplies

SCHURTER expands the product portfolio, introducing the radial leaded varistors AVTS, AVTP and AVTT

(PresseBox) (Endingen, ) To add a third protective element to fuses and filters, SCHURTER now also offers overvoltage protection components, thereby making it possible for users to obtain all components required for the electrical protection of their electronic appliances from one source.

SCHURTER now offers radial leaded varistors, also referred to as MOV (Metal Oxide Varistors), which help to protect electronic circuits against surge transients, such as can be caused by lightning strikes and switching of contacts and inductive loads. Varistors are suited to a wide variety of applications including switching mode power supplies, ballasts and motor protection used in areas such as industry, telecom and medical technology as well as in consumer goods.

There are different types for various application fields available: AVTS for secondary protection, AVTP for primary protection, and AVTT for 3-phase applications. The varistors, all approved according to IEC 61051, UL 1449, UL 1414 as well as CSA C22.2 and conforming to RoHS regulations, are available in plastic bags, taped and reeled and in ammo packaging.
