Open fame power supplies meet eco standards
23 February 2015 
The RAC48/OF and RAC60/OF are now ready to order. They comply with worldwide safety standards as well as the European ErP Directive. Suitable uses are industrial controls, computing, test gear, network equipment and medical applications. The compact AC/DC PSUs can typically operate in high ambient temperatures without active cooling. Specified range is -20 to 50°C at 100% load and up to 70°C at derated load. The power supplies deliver high efficiency, sub-0.5W standby power and a long hold-up time of 60ms. Both models are available with output voltages of five, 12, 15 and 24V DC, adjustable via the on-board pre-set. The DC outputs are protected with over-current protection, over-voltage protection and hiccup short circuit protection. The universal input voltage range is 90 to 265V AC and 3kV AC/60s isolation. Certifications include EN55022 EMC (Class B), IEC 60950-1 CB Report, EMC LVD CE mark, FCC and UL 60950-1 certificates. The MTBF lifetime (MIL-HDBK217F) is approximately 450,000 hours. All units are covered by a three-year warranty.
