RONUI500 Series AC/DC Power Supplies

RONUI500 Series industrial AC/DC power supplies deliver up to 500 watts of power with no minimum load requirement. These high-efficiency AC/DC power supplies accept 85 to 264V AC universal input, offer 3,000V AC reinforced insulation and meet the UL/IEC/EN 62368-1 safety standard. OVC III-compliant RONUI500 supplies measure 4.6 x 2.4 x 0.5 inches (116.8 x 61 x 12.77 millimeters) with open and enclosed versions, offer up to 93% efficiency and feature power good signal, remote ON/OFF, current share function and low standby power. Built-in safeguards include over temperature, overcurrent, overvoltage and short circuit protection. Well-suited for rugged environments, the RONUI500 is appropriate for 5G communications, defense, robotics and factory automation applications. The RONUI500 Series industrial AC/DC power supplies comply with RoHS and REACH regulations.
