Solid State Relays for AC Power Switching Applications Requiring High-Rel and High Safety

Series KA/LA - Teledyne Defense Electronics Relays & Coax Switch

Series KA/LA solid-state relays are designed for use in AC power switching applications where safety and reliability are primary concerns. They are ideal for resistive and reactive loads with power factors as low as 0.2. Inverse parallel SCRs are configured for zero-​voltage turn on. The relays are available with thermal protection and thermal trip status.
