The Phoenix Contact TRIO-PS-2G/1AC/24DC/20 is a primary-switched, single-phase AC-DC DIN rail power supply designed for industrial automation and machine building applications. It converts 85-264 VAC or 99-275 VDC input voltage to a regulated 24 VDC output at 20 A continuous current, delivering up to 480 W rated power. The unit features push-in connection technology for tool-free wiring of solid and stranded conductors, a dynamic boost function providing 150% nominal current for five seconds to handle inrush loads, and adjustable output voltage. Its compact, rugged design supports operation across an extended temperature range from -25°C to +70°C with device startup at -40°C. The TRIO POWER series offers multicolor LED diagnostics, optional signal relay contacts for status monitoring, and space-saving side-by-side mounting capability, making it ideal for demanding industrial environments requiring high system availability.
