HS3D5HV048E230 Lovato SOLID STATE RELAY 3P 48A WITH HEAT SINK

Why Choose the Lovato HS3D5HV048E230 Solid State Relay?

The Lovato HS3D5HV048E230 is a high-performance three-phase solid state relay with three controlled phases, designed for reliable electronic switching of resistive and motor loads in industrial control and automation systems. As part of the Lovato HS3D solid state relay series, it is supplied complete with a heat sink for effective thermal management and convenient control-panel installation.

This solid state relay uses SCR switching technology with zero-crossing operation, providing fast, silent and wear-free switching without conventional mechanical contacts. Zero-crossing switching helps minimise electrical disturbances when switching compatible AC loads, while the solid state construction makes the HS3D5HV048E230 particularly suitable for applications requiring frequent switching cycles and dependable long-term operation.

With a rated operating current of 48 A for AC-51 resistive loads at 40 °C, a 24–520 V AC rated operating voltage and a wide 24–255 V AC/DC control input, the HS3D5HV048E230 provides versatile control of demanding three-phase industrial loads. Its integrated heat sink, screw terminals and robust electrical isolation make it suitable for industrial heating, machinery and automation installations.
