Mean Well HDR DIN Rail power supplies are available in 15W, 30W, or 60W and feature an ultra-slim, step shape plastic housing. The HDR family specially adopts the European Union standard DIN EN43880 and slim design with a height of 90mm and the width are only 1SU to 3SU (17.5mm/35mm/52.5mm). They also feature efficiencies up to 91%, adjustable (10%) DC output voltage, and a working temperature range of -30DegreeC to +70DegreeC. Typical applications include building automation, household control system, industrial control system, factory automation and electro-mechanical apparatus.
