With rugged, zinc-plated steel housing measuring between 32mm and 115mm wide, the Trio occupies less space than most DIN-rail-mounted power supplies. The Trio addresses applications requiring 2.5 to 20 amps of 24VDC power. The Trio has a Mean Time Between Failure (MTBF) rating of >500,000 hours, in accordance with IEC 61709, at nominal load and high 40ºC test standard. Backed by a 5-year warranty, the TRIO operates in temperatures ranging from zero to 70ºC and features a 55ºC nominal operating temperature without de-rating. Other features include built-in LED diagnostic indication, adjustable 22.5-29.5VDC output and three DC grounding terminals.
