Product Description

The Phoenix Contact TRIO-PS/1AC/24DC/20 is a high-performance, primary-switched power supply unit designed for DIN rail mounting in industrial automation systems. It converts single-phase AC input (85–264 V) into a stable 24 V DC output with a current capacity of 20 A, delivering up to 480 W of power. This power supply features a rugged metal housing, operates within a wide temperature range from -25°C to +70°C, and boasts a high mean time between failures (MTBF) of over 500,000 hours, ensuring long-term reliability. The output voltage is adjustable via the front panel to compensate for voltage drops, and the unit includes comprehensive protection mechanisms such as overvoltage protection and active current limitation. It's ideal for powering control devices, sensors, and other equipment in demanding industrial environments.​
