The primary-switched and regulated switching power supplies deliver a safe extra-low voltage (SELV according to EN60950) with radio interference level B according to EN55011 and EN55022. They are tested for use in industrial and public networks. Overload protection and continuous short-circuit strength ensure high device safety. Rated input voltage at 50/60 Hz: 100-240VAC, rated output voltage: 24V/12VDC, rated output current: 0.35A/20 mA
