The Lovato HS1C6HV025D024 is a complete single-phase solid state relay (SSR) with integrated heatsink, designed for reliable electronic switching of resistive AC loads in industrial control applications. As part of the Lovato HS1C solid state relay series, it combines semiconductor switching technology, effective thermal management and convenient mounting in a ready-to-install assembly.
The HS1C6HV025D024 uses an SCR semiconductor output with zero-crossing switching, helping reduce electrical disturbances when compatible AC loads are switched. It accepts a 4–32 V DC control signal and switches loads across a wide 48–600 V AC rated operating range, making it suitable for interfacing with PLC outputs, temperature controllers and other low-voltage electronic control equipment.
Rated at 25 A AC-51 at 40 °C and 22 A AC-51 at 55 °C for resistive loads, the HS1C6HV025D024 is supplied complete with its heatsink for simplified thermal management. Its 1200 V blocking voltage, 520 A surge-current capability, VDR output protection and 5000 V input-to-output isolation make it a dependable solution for industrial heating, process control and automation systems.
Solid state relays switch electrical loads electronically without the moving contacts found in conventional electromechanical relays and contactors. This enables silent operation, rapid response and excellent switching endurance, making SSR technology particularly valuable for applications involving frequent ON/OFF cycles such as industrial heating and process-temperature control.
The Lovato HS1C6HV025D024 combines these advantages with an integrated heatsink, simplifying component selection and installation compared with an SSR requiring a separately specified heatsink. Its 25 A AC-51 rating, broad 48–600 V AC load range and 4–32 V DC control input provide a practical solution for PLC-controlled industrial panels and automated machinery requiring reliable semiconductor switching.
