Littelfuse KSDB220 is a compact and reliable solid-state time delay relay. It features a 1A steady state and 10A inrush load rating, with 0.25-inch male quick connect terminals for easy installation. With a wide input tolerance of ±20% and humidity resistance up to 95%, it ensures accurate and consistent performance. The encapsulated circuitry and insulation resistance of ≥100 add to its safety and durability. The relay consumes less power (≤2VA) and provides a fast reset time of ≤150ms. Other notable features include a repeat accuracy of ±0.5% or 20ms, a time delay tolerance of ±5%, and a dielectric breakdown of ≥2000V. It has an output voltage drop of ≅2.5V @ 1A and an open state leakage current of ≅5A @ 230V AC. Moreover, the initiate time is ≤20ms, making it highly responsive.
