Littelfuse DSTUA3 is an encapsulated circuitry time delay relay. It features a 0.7 A steady state and 10 A inrush output load rating, with push-on terminal blocks for up to #14 AWG wire. The input AC line frequency can be set to 50 or 60 Hz, with an input tolerance of -20% to 10%. The device offers surge protection according to IEEE C62.41-1991 Level A standards, and has a reset time of ≤300 ms. With a repeat accuracy of ±0.1% or ±20 ms, and a setpoint vs ambient temperature and operating voltage accuracy of ≤±2% or 50 ms, the DSTUA3 provides reliable and precise time delay control. The product also includes a microcontroller-based time delay type with a ceramic resonator and watchdog circuitry, and an initiate time of ≤32 ms for single shot and delay-on-break operations. The device is compatible with 6 switches for time delay adjustment, and 2 switches for selecting 1 of 4 multipliers. With a dielectric breakdown of ≥2000V terminals to mounting surface and an output voltage drop of 2.5V @ 0.7A, the DSTUA3 is a versatile and dependable time delay relay for various applications.
