Cosel TU series of AC-DC converters
RS Components (RS) is stocking new ranges of AC-DC and DC-DC converters from power supply manufacturer Cosel. 

The brand is well-known in Japan and the US for manufacturing reliable and high-quality power supplies, including ultra-small AC-DC switching supplies and state-of the-art DC-DC converters. RS now introducing more than 500 new products to the range, many with five-year warranties.

Key new products in the range include the compact GHA300F and GHA500F series of industry-standard 76 x 102mm (3 x 5in) footprint AC-DC converters with a maximum power output of 500W. Offering industrial and medical safety approvals and fitting 1U standard-size applications, features of the supplies include built-in fan, low leakage current, internal dual fuses and a harmonic attenuator that meets IEC61000-3-2 Class A for EMC compliance. Other features include built-in power factor correction (PFC) circuitry for decreased AC input capacity, as well as built-in inrush current, overcurrent and overvoltage protection circuitry. Various options are also available including remote On/Off, AUX1/2 (12/5V), and power-good signal.

Other important product ranges are the TUHS and TUNS series of AC-DC converters. The TUHS series offers a compact footprint for improved design flexibility. Featuring high efficiency and low standby power, the units accept an 85–264V AC or 120–370V DC universal input voltage. The TUNS high-reliability 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.

A further addition is the CHS range of compact, high-density and high-reliability isolated DC-DC converters, which offer high efficiencies at up to 92.5% and come in the quarter-brick standard size for applications such as telecommunications. Integrated features include overcurrent, overvoltage and thermal-protection circuitry and remote ON/OFF.
