Littelfuse KRDR120A0 is a compact and reliable solid-state relay. It has a load rating of 10 A resistive at 125 V ac, 5 A at 230 V ac/28 V dc, and 1/4 hp at 125 V ac. The termination type is 0.25 in. male quick connect terminals. It operates within an input tolerance of -15% to 20% and handles humidity up to 95% non-condensing. With a repeat accuracy of ±0.5% or 20 ms (whichever is greater), it ensures precise control. The relay has encapsulated circuitry, low power consumption (≤2 W), and a time delay tolerance of ≤±5%. It resets in ≤150 ms and has a long lifespan (Electrical: 1 x 10⁵; Mechanical: 1 x 10⁷). The DC units are reverse polarity protected, and the input DC ripple is ≤10%. It provides a maximum output voltage of 250 V.
