SSR solid state relay uses inflaming retarding engineering plastic shell, epoxy resin encapsulation, and screw terminal connection. This series of solid-state relays 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: Model: RSZS-40DA-R Control Mode: DC-AC Load Voltage: 24-380VAC Load Current: 40A Control Voltage: 3-32VDC Control Current: DC3-25mA Working voltage: 250V On voltage: ?1V One-off Time: ?10ms Off leakage Current: ?2mA Installation Method : Bolt Fixed Working Indication: LED Solid State Relay Fotek RSZS-40DA-R
