描述

The A2425E is a 25A solid-state relay designed for AC load switching with an 18–36 VAC control input range and 24–280 VAC output operating voltage. It features SCR output technology suitable for heavy industrial loads, with zero-crossing turn-on for resistive loads or random-fire capability for inductive loads, and supports both AC and DC control configurations. The relay delivers a maximum load current of 25 A (Arms) with a maximum on-state voltage drop of 1.6 Vpk, a maximum 1-cycle surge current of 250 Apk at 60 Hz, and a thermal resistance of 1.02 °C/W (junction to case). It is rated for ambient operating temperatures from -40 °C to +80 °C, features 4000 Vrms dielectric strength between input/output/base, and is housed in thermally conductive epoxy encapsulation with screw terminals. The A2425E is ideal for industrial automation, HVAC systems, motor control, and heating applications requiring reliable AC switching with panel-mount convenience and UL/CSA/VDE approval.
