Littelfuse TDS120ALD is a 10A resistive output load rating device, capable of operating at 120/240V AC and 28V DC. It utilizes a Magnal 11-pin plug-in termination type and supports an input AC line frequency of 50/60Hz. With a repeat accuracy of ±0.1% or 20ms (whichever is greater) and a setpoint tolerance of ≤±5%, this product offers precise control. It consumes ≤3.25W of power and has a reset time of ≤50ms. The time delay type is digital, and the unit has a long electrical and mechanical life of 1x10⁶ and 1x10⁷, respectively. The recycle time is ≤150ms, and the initiate time is ≤60ms. The setting accuracy is ≤±2% or 50ms (whichever is greater), and the product provides indication through an LED glow during timing, along with energizing the relay.
