RS Components has added a further 500 products to the ranges of high-reliability power supplies it distributes under the Cosel brand. The range includes ultrasmall AC/DC switching supplies and state-of the-art DC/DC convertors, all competitively priced, available from stock, and many carrying five-year warranties.
Key new products in the range include the high-density GHA300F and GHA500F series of industry-standard 3 x 5in footprint units (pictured) with power outputs up to 500W. These units come with inbuilt cooling fans, internal dual fuses and a harmonic attenuator that meets IEC61000-3-2 Class A for EMC compliance. Other features include low leakage current, integrated power factor correction, and inbuilt inrush current, overcurrent and overvoltage protection circuitry.
The TUHS series of compact AC/DC convertors combine high efficiency and low standby power, with 85–264V AC or 120–370V DC universal inputs. TUNS high-reliability AC/DC converters come with PFC circuitry, making them suitable for conduction cooling. Other features include an 85–264V AC input voltage range and built-in overcurrent, overvoltage and thermal protection circuits.
The CHS range of compact, high-density and high-reliability isolated DC/DC convertors offer high efficiencies at up to 92.5% and come in the quarter-brick standard size. Integrated features include overcurrent, overvoltage and thermal-protection circuitry.
