Feature:1. Two-way SCR output is suitable for commercial heavy industrial applications with reliable performance2. Ultra-low input current, low output off-state leakage current, on-state voltage drop3. Contain R-C buffer with standard output, pass through 100% load current aging test4. Come with LED light output indication, transparent protective cover provides additional protection for users5. SSR series three-phase solid state electrical appliances adopt flame-retardant engineering plastic shell with epoxy resin potting, threaded terminal wiring, with strong structure, high impact resistance, strong vibration resistance6. The input end drive current is small and can be easily interfaced with computer terminals and various digital program-controlled circuits. Which is widely used in petrochemical equipment, food machinery, packaging machinery, textile machinery, CNC machine tools, plastic machinery, fitness equipment, entertainment facilities and other automation control fields7. Especially suitable for harsh environments such as corrosion, wetness, dust-proof, explosion-proof requirements, and occasion swith frequent switching, which is a replacement product of AC contactorSpecification:Item Type: 3 Phase Solid State RelayMaterial: ABSPurpose: RelayModel: SSR-3 D4840 40ALoad Current: 40AControl Current: 20mAPassed European Community CE certification and international IS09000 certification.Package List:1 x 3 Phase Solid State RelayNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
