Littelfuse KSD1420 is a compact and reliable solid-state relay designed for a load rating of 1A steady state and 10A inrush at 60°C. It features 0.25 in. (6.35 mm) male quick connect terminals for easy installation. With an input AC line frequency of 50/60 Hz and a tolerance of ±20%, it provides accurate and stable performance. The relay operates in high humidity conditions (95% relative: non-condensing) and offers repeat accuracy of ±0.5% or 20ms, whichever is greater. It has excellent insulation resistance (≥100 Ω) and dielectric breakdown (≥2000V terminals to mounting surface). With a quick recycle time of ≤150ms and a time delay tolerance of ±5%, it ensures efficient and precise switching. The relay has a low output voltage drop (≅2.5V @ 1A) and open state leakage current of ≅7A @ 230V AC, while consuming a minimum output holding current of ≤40mA. Its encapsulated circuitry ensures durability and protection.
