SSR solid state relay uses inflaming retarding engineering plastic shell, epoxy resin encapsulation, and screw terminal connection. This series of solid-state relay has high structural strength, impact resistance, and strong resistance to viability. The low input drives current makes it convenient to connect with a computer terminal and various digital programmable interface circuits. Features: Reliable SMT technology High ultra insulation resistance over 50M?/500V DC High dielectric over 2.5KV Low EMI/EFI & surge by zero cross trigger method High surge current over 410A/one cycle (60Hz) High surge voltage duration by the snubber circuit Specification: Theory : Static relay Contact load: Low power Use : General Purpose Energy source: AC Voltage: 250 V Customized: Yes Model Number: SSR 3-40AA Output Current: 40A Uses Industrial automation control panels Heating and temperature control systems Motor and lighting load switching PLC and machine control applications Electrical equipment power control Package Includes: 1 x Tense Solid State Relay Module SSR3-40AA
