Reliable 48W and 60W open-frame AC/DC supplies need no active cooling

Recom's new RAC48/OF and RAC60/OF Class II open-frame power supplies offer 48W or 60W output power offer high performance, even at high ambient temperatures. With an operating temperature range of -20C to +50C at 100% load and up to 70C at derated load, there is typically no need for active cooling, says the company. Built with high-quality components to ensure a long trouble-free life, the compact AC/DC modules are highly efficient, have a long hold-up time (60ms) and are also compliant with the European ErP directive (<0.5W in standby). Both series are available with output voltages of 5VDC, 12VDC, 15VDC and 24VDC, adjustable via the on-board preset. The DC outputs are fully protected with OCP, OVP and hiccup SCP. With their universal input voltage range of 90V to 265VAC and 3kVAC/ one minute isolation, they are suitable for worldwide use. The converters are fully certified with 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, says the company.
