RAV-LDEZSERIES SURGE PROTECTORS ●RAV-LDEZ: Designed specifically for use in AC power line applications. This model uses specially treated discharge electrodes for greatly enhanced noise immunity test and surge life making it optimum for the protection of single-phase power supply circuits. Safety Approvals : UL-1449 : C22.2 No. 8 M1986 UL CSA File No . E143446 LR105073 ●RAV-401LDEZ SURGE ABSORBERS ●RAV-781LDEZ ●Use of Surge Protectors: Okaya Surge protectors in combination with Okaya XYE series filter capacitors offer superb lightning surge suppression. Capacitor XYE-104332 will equalize excessive currents aiding the surge protector in absorbing the lightning surge. This parts combination is equally effective against severe noise. ●Noise Margin Test: Noise margin testing usually requires the physical disconnection of lightning surge protection components. Such disconnection often is difficult and time consuming. Okaya's RAV-LDEZ series allow noise margin testing without any such disconnection as they are designed to withstand the rigors of testing.
