The third generation of Step Power power supplies keeps the same footprints as the previous version, measuring 55 mm deep and with widths starting at 18 mm, but efficiency and power density have been increased. These power supplies have EN 60355-1 certification, are UL 61010-listed and have Class I, Div. 2 approval. They can accept either an ac or dc input, so they can adapt to a variety of applications. The wide output range lets users adjust to their specific needs. They also are available in the company’s push-in technology for easy wiring.
