New 300W AC-DC that can stand the heat; 90% power at +85°C & high efficiencies remove need to overrate & overspend

Wednesday, July 17, 2019

ITL300 imageFiDUS Power is today releasing the exciting ITL300 series of 3 x 5”, open frame AC-DC power supplies. Complementing the extensive range of innovative open frame options from FiDUS, the ITL300 offers an edge to system designers dealing with higher enclosure temperatures.

The ITL300 can deliver 300W of power when fan cooled with 10CFM and 200W when used in free air convection. The unit also has a peak capability of 400W for 200ms and is approved to UL/IEC 60950-1 ITE safety standards. Flexibility is afforded with 7 single output models between 12-54VDC on offer and the series provides an integrated 12V fan output, remote sense and power fail signal all as standard.

Where the ITL300 stands out, is in its thermal performance. The range has been designed to achieve optimum thermal dissipation and minimal hot spots to reduce the temperature of critical components. This allows a leading maximum operating temperature of +85°C and significantly reduces the level of derating at +50-70°C ambients where rival units generally drop to 50% power. With the ITL300, when fan cooled it will offer a whopping 90% of its maximum 300W output even at +85°C. When convection cooled it can still provide over 140W at +70°C and 100W at +85°C.

For applications facing ambient temperatures over +50°C, the ITL300 is uniquely placed to remove the need for overrating, oversizing and overspending on the power supply. The ITL300 is also between 93-95% efficient at full load, so will itself contribute very little waste heat.

Notably, the ITL300 is also very competitively priced suiting a wide range of ITE, industrial and technology product designs; whether hot or not!

If you have an application facing higher internal temperatures, get in touch for a free engineering sample to evaluate.
