DESCRIPCIÓN
The D18F is a DC voltage sensor relay designed for aerospace power applications, featuring 2PDT main contacts with a 10-amp rating at 28 VDC. It incorporates a dropout time delay function that maintains relay energization for 200–400 milliseconds when input voltage drops below 21.5 ±0.5 VDC but remains above 15 VDC, providing enhanced circuit protection and stability. The device operates with a pick-up voltage of 24.5 ±0.5 VDC and a drop-out voltage of 21.5 ±0.5 VDC, with a maximum pick-up time of 125 milliseconds. Built with aluminum metal can construction and hermetic sealed contacts, the D18F meets MIL-R-6106 requirements and operates reliably across -55°C to +85°C. This relay is ideal for aircraft electrical systems, power distribution networks, and other aerospace applications requiring precise voltage monitoring and switching control.
