描述

A1225E is a 25-ampere solid-state relay designed for heavy industrial AC load switching with 18-36 VAC control input and 24-140 VAC output capability. The relay features SCR output technology with zero voltage or instantaneous turn-on switching options, direct bond copper substrate construction, and a thermal resistance of 0.8°C/W (junction to case). It is UL/CSA/TUV approved and CE compliant to EN60950-1, with EMC compliance to Level 3, making it suitable for demanding industrial environments. The device offers maximum on-state voltage drop of 1.15 Vrms at rated current, maximum 1-cycle surge current of 239 Apk (50 Hz) or 250 Apk (60 Hz), and operates reliably across an ambient temperature range of -40°C to +80°C. Common applications include motor control, heating element switching, and other heavy industrial loads requiring robust, long-life solid-state switching with minimal maintenance.
