High Energy Varistors E Series
About the company HOW IT STARTED? The beginnings of the company date back to the early s, when seventie the companywas a part of the former world-wide known ISKRA Group - TOZD Keramika in DO ISKRA IEZE Ljubljana, puted producer re of technical and high frequency ceramics.
GENERAL COMPANY DATA AND ITS STRATEGY Varsi, d.o.o. decided to carry on with the program rs, of couplings varisto and temperature probes, which had beenf a part o the production program also in the former Iskra TOZD Keramika ince 1983.s Varsi, d.o.o. therefore continues the tradition and upgrades the past experiences in the production of nology high tech ceramicson the base of its own knowledge and research. The company has dedicated itself to total customer tion. satisfac Market research - product development - purchase production - testing & control - sales - environmental protection - these are the activities incorporated in the company managing. Varsi, d.o.o. strives for perfection on all levels of its activity. The company ison present all major world markets, daily facing strong competition. It is therefore important to offer quality highproducts at reasonable costs. The company has been successful, because: It has been able to satisfy and respect customers' ons expectati and requirements It has been balancing the internal costs properly tion in correla with the care for good realization of processes It has been able to evaluate its efficiency It constantly monitors its performance and eliminates easons the for r any possible mistakes It creates sufficient new value (added value) It takes care for qualifications of the employees,g stressin the importance of each single employee being a relevant t par of the chain It confirms its accomplishments by international standard s: UL, CSA, ISO 9001:2000, RoHS
COMPANY RESEARCH AND DEVELOPMENT ACTIVITIES VARSI, d.o.o. works on the base of its own knowledge ch. andItsresear R&D activity is regulated within the company R&D Department. In May 1999 Varsi, d.o.o. established its own, independent esearch &r development group named ISVAR , with the purpose to upgrade the link between the existing production and ch resear spheres. The activity well generates the link between basic and cationappli research, technological parameters in the varistor manufacturing ocess. pr

General Data
Varistors, also called VDRs (Voltage Dependent Resistors) , show a high degree of non-linearity between their ce resistan values and the applied voltage s. A metal oxide varistor is a voltage dependent, symmetrical non-linear resistor. Its resistance decreases with reasing the inc .VÎą , where voltage. This can be expressed by the equation I = K I = current through the varistor V = voltage K = material constant Îą = non-linear index Varistor resistance is a non-linear inverse function of d thevoltage. applie At rated voltage the varistor resistance is high. When a higher transient voltage appearsacross the varistor, its resistance sharply decreases ow to value. a l This transient voltage is clamped to a safe level and the energy ent in the is dissipated transi in the varistor. byThere the equipment is protected against overvoltages.
Varistors are intended for safeguarding sensitive electronic componen ts against voltage pulses of various sources. Varistors are also used for stabilizing higher DC voltages. Should a high voltage pulse occur, the `svaristor resistancewould immediatellyshift from a very high value to a level of good conductance. The varistor would absorb the energy of the pulse and decrease the voltage to a safe , level thereby protecting the electronic component against damages. CONSTRUCTION A varistor is primarily made of zinc oxide, formed configuration into disc and sintered together with other metal oxide additives at high temperature. The tablet-shaped varistor ceramics is silver electroded nd fired. a Copper leads are soldered to the electrodes. Discs can be either epoxy coated or put into a plastic . housing STANDARD VARISTORS The basic design of metal oxide varistors consists ristors of Discwith Va Radial Leads and High Energy Varistors. The standard range of varistors with radial leads covers diameters the of 5, 7, 10, 14, and 20 18 mm. High Energy types are available in the 25, 32, and40, 80mm 60 version s.

High Energy Varistors - E 25, E32, E40 Series
Description The E types are heavy-duty metal oxide varistors designed mainly for industrial applications. They offer excellent surge protection for various electronic equipment such as: traffic and railway signal systems, communication equipment, waterworks, automatic control devices for power distribution, oil drilling and mining equipment (dredgers, cranes, etc.). The E housings offer excellent protection also when they are exposed to different kinds of vibrations, dust, moisture, etc. The advantages of the E Series are: rigid terminals for good wire contact, solid plastic housing for secure mounting, higher insulation resistance (polyurethane filling and plastic housing).

High Energy Varistors - E60 Series
Description The E 60 types are heavy-duty metal oxide varistors designed mainly for industrial applications. They offer excellent surge protection for various electronic equipment such as: traffic and railway signal systems, communication equipment, waterworks, automatic control devices for power distribution, oil drilling and mining equipment (dredgers, cranes, etc.). The E60 housings offer excellent protection also when they are exposed to different kinds of vibrations, dust, moisture, etc. The advantages 60 of the E Series are: rigid terminals for good wire contact, solid plastic housing for secure mounting, higher insulation resistance (polyurethane filling and plastic housing) .
