The SH48A125 is a High Industrial Performance (HIPpak) solid-state relay for demanding AC load switching. It is rated for a load voltage of 24-510 Vac and a continuous load current of 125A. This model features a zero-cross switching mechanism to minimize electromagnetic interference, controlled by a wide input voltage range of 20-265 Vac/dc. Key electrical characteristics include a peak voltage of 1200 Vpeak, a maximum non-repetitive surge current of 2200 A, and 4000 Vrms input-output isolation. Its robust design, including IP20 touch-proof flaps, makes it ideal for industrial applications such as controlling resistive heating elements and high-power lighting systems.
