High efficiency AC/DC power supplies

High efficiency internal and external AC/DC power supplies from Gresham Power Electronics meet CEC Level VI Energy Efficiency Standards, which come into effect on 10 February 2016. OEMs intending to export their products to the US will be required to meet this standard.

The TE60 family of external power supplies has an output power ranging from 10W to 60W, with higher power versions to follow. Also available is the TB65 open frame version.

Desktop and wall plug models are available with regulated output power and short circuit and thermal protection.

TB65 open frame models are said by the supplier to offer ‘superior EMC/EMI compliance, RF and surge immunity’. With a footprint of 2 x 3.5in and a height of 1.3in, the series provides up to 65W of convection cooled output power. Models in the TB65 range accept an input in the range from 90 to 264V AC and can be supplied with outputs of 12V, 15V, 24V and 48V.
