FiDUS launches the world’s smallest 40W AC-DC open frame power supply

Thursday, March 09, 2017

TCF40FiDUS Power has announced the TCF40 series of single output, open frame AC-DC power supplies. This series of product is capable of delivering 40W of power, convection cooled and a peak rating of 50W for 60s. We believe this product to be the smallest of this type in the world, measuring only 76.2 x 38.1 x 23.5mm. This enables it to be used in a multitude of applications where system designers are looking to lead their markets with size reduction of end equipment. The AC-DC power supply is also well priced with a standard 1 off cost of £18.65, which is very competitive in our market.

How does the size of this AC-DC power supply compare?

This 1.5 x 3” footprint sees a steady evolution of the 40W open frame area; 20 years ago you would have been offered a 3 x 5” package size. More recently the 2 x 3” footprint has become prevalent; the TCF40 sees a further 25% reduction in size. The range consists of seven different models from 5 to 48VDC output. The operating temperature range is 0 - 70degC with full load to 50degC.

Efficiency and engineering samples

The series is very energy efficient, consuming less than 0.1W during no load conditions and with efficiencies up to 91% limits waste heat into your system, runs cooler and helps maintain a good product lifetime. The product operates from 90 – 264VAC input with no derating and meets EN55022 (EN55032) class B for both conducted and radiated noise, making the path to compliance much simpler. The TCF40 is certified to IEC/UL/CSA/EN60950-1 for safety.

As with all supplies from FiDUS Power, the TCF40 is protected by a 5-year warranty, competitively priced and available to be purchased direct from our website. Why not take a look at the TCF40 product page for further details including 3D models?
