Reliable power supplies with low no-load consumption

 

With the RAC04/277 (4 watt) and RAC10/277 (10 watt) series, RECOM extends its broad product portfolio of highly efficient power supplies with a power range of up to 10 watts. These new mini power supplies are suitable for PCB mounting and are characterized by a very low no-load consumption of only 50mW for the 4W modules and only 300mW for the 10W modules. Therefore the mini power supplies are particularly energy-saving and consume less than one tenth of the requirements of the EuP directive.

 

Both series offer a variety of output voltages from 3.3VDC up to 24VDC as well as dual outputs of ±5VDC, ±12VDC or ±15VDC (only RAC10/277). Additionally the RAC04/277 series is also available with an asymmetric 5/12VDC output. Due to its universal input voltage range of 80V to 305V, they are particularly suitable for worldwide use, since this range covers all standard voltages.

With an operating temperature range of -20°C to +80°C for the RAC04/277 and -20°C to +75°C for the RAC10/277, there is typically no need for heat sinks or active cooling. The series are very impressive with their high efficiency of up to 80% and input-to-output isolation of 3.75kVAC.

Both series meet EN55022 class B, which is necessary for home use, without external filter components which could otherwise decrease system efficiency. The lifetime according to MTBF (MIL-HDBK217F) is approximately 500000 hours. The converters comply with EN/UL60950-1 and come complete with a 3 year warranty.
