R·A·V-L-A SERIES

SURGE PROTECTIVE DEVICES

Power surges, both voltage and current, are occurring

Structure

continually in today's power systems. Whether they

occur naturally, such as from lightning and static

electricity; or are man made, such as inductive surges

from motor, transformers, solenoids, etc. power

surges are a fact of life. These power surges have a

very high voltage and current level as compared to

electrical noise.

Recent developments in electronic designs have

tended toward smaller and higher density packaging

of circuitry. This results in a greater susceptibility to

surges. Once attacked by a surge, electronic circuits

of electronic equipment must be aware of, and be able

to deal with, power surges in product design.

OKAYA's R·A·V surge absorbers are designed to

assist in dealing with the problem of power surges.

The R·A·V series is a unique new approach which

combines the features of two well known

FEATURES

The R·A·V Surge Absorber is applicable for the

protection of many types of electrical equipment. The

R·A·V has the following features:

1) Large capacity surge protection

2) Fast response time

technologies. Combining the high speed capabilities

of Metal Oxide Varistor (MOV) with the large power

handling capability of Gas Arrester, OKAYA has

developed a product which can clamp power surges

faster than gas arrester alone and handle large power

surges far beyond the capability of MOV.

3) Good endurance to repetitive lightning

4) High clipping performance

5) Low internal capacitance

6) No environmentally hazardous materials

OPERATING PRINCIPAL

Surge Wave

The R·A·V connected between lines will shunt the

surge from one side of the line to the other. The high

speed varistor quickly shunts the surge until the

slower, but more powerful gas arrester takes over.

This allows the gas arrester to handle the high energy

portion of the surge and protect the MOV from

damage. This interaction of the R·A·V assures safe

handling of the power surge and long life stability to

the MOV.
