The Crydom LVD75B40 Solid State Relay switches DC loads up to 40 A at 3–75 VDC with an 11.5–12 VDC input. It uses an SPST-NO configuration, providing a normally open output that closes when the input is energized. As a solid-state device, it offers silent switching with no moving parts, making it suitable for DC-powered control circuits in industrial panels where the drive voltage is 11.5–12 VDC and the load voltage is within 3–75 VDC.
