Littelfuse ASTUD3 is an encapsulated time delay relay with a steady state output load rating of 0.7 A and 10 A inrush. It has push-on terminal blocks for up to #14 AWG wire, with an input tolerance of 9 - 110 V dc and humidity resistance of 95% relative non-condensing. The relay has a repeat accuracy of ±1% or 50 ms, setpoint accuracy of ≤±2% or 50 ms, and time delay tolerance of ±2% or ±50 ms. It features a microcontroller-based time delay type with a ceramic resonator and watchdog circuitry. The reset time is ≤300 ms and it has a dielectric breakdown of ≥2000V terminals to mounting surface. The ASTUD3 has an output voltage drop of ≅1.5V @ 0.7 A and supports input DC ripple of ≤10%. It employs a knob with dial adjustment type and offers surge protection according to IEEE C62.41-1991 Level A standards.
