DRL ac-dc DIN-rail-mount power supplies offer efficiencies of up to 90%, reducing waste heat and allowing the use of narrow-width package sizes ranging from 18 mm for the 10-W model to 72 mm for the 100-W model. Less space on the rail provides additional room for other components or the use of smaller enclosures. The series has an operating input range of 85 to 264 Vac and can withstand 300 Vac for 5 s. The units have a Class II construction (double insulation) and do not require an earth ground connection. Input to output isolation is 3,000 Vac.
