Surge Absorber
In recent telecommunication and industrial equipmennts such as telephones, computers, facsimiles and others, many electric devices are used with high integration. When surges or noizes are occurred in their circuits, serious problems are caused as their electric devices are often destroyed by high voltage impulses. Since the surge results from lightning, electro-magnetic induction and ststic electricity, it is really difficult to prevent the occurrence of the surge. Therefore, surge absorbers are essential to protect electric equipments from the surge.
ELEVAM provides many kind of surge absobers which can instantly absorb the surge utilizing gas discharge. Especially, we efforts to line up low-voltage devices working for static electricity surges.
Features
ELEVAM's surgeabsorbers have features described below.
1)Low cost and high quality through mass production.
2)Quick response for surges and large current capacity in spite of small size.
3)High insulation resistance, low capacitance,and low leakage current.
4)Long life by the stability against repeated surges.
5)Discharge voltage agaist current characteristics are excellent.
6)Failure mode is open.
Applications
1) Protection of semiconductors and condensors in power supplies (SA-E170, SA-E230, SA-220(3))
2) Protection of TV circuits (SA-E80, SA-E140)
3) Protection of TV high-voltage circuits (SA-E230)
4) Protection of breaker contacts ( SA-E230, SA-E350)
5) Protection of circuits in disaster prevention equipments (SA-80SS)
6) Protection of antenna circuits ( SA-80SS, SA-140SS, SA-200SS)
7) Telephone sets (incliding cord-less telephone ) (SA-80SS, SA-E500)
8) Protection of PBX ( SA-80(3), SA-180(3), SA-220(3))
9) Protection from electrostatic surge on audio systems ( SA-80SS, SA-200SS)
