Power adapters are compact boost for industrial applications

The TGA330 series power adapters from Tumbler Technologies and Trumpower can achieve a power density greater than 100W/cubic inch, addressing the need for compact 330W solutions for industrial and ITE applications.

The profile is a slim 7.87in (length) by 3.94 in (width) by 1.06in (height) and the devices are available with either a 19.5V or 24V output. The power adapter is furnished with an IEC 320/C14 AC inlet and has a standard output connector of a 4 pin DIN plug. Additional connector and cable options are available on request.

Operating at a 90 to 264 VAC universal input, the series supports operating altitudes up to 5,000 metres and operating temperatures between 0 degrees C  and +70 degrees C ambient, while derating linearly from 100 per cent load at +40 degrees C to 60 per cent load at +70 degrees C.

The power supply is also equipped with standard over current, over temperature, and over voltage protections. It has 300,000 hours-minimum MTBF at full load, 25 degrees C ambient, calculated per SR332.

The power supply series carries the CE marking, is RoHS compliant, and is approved by UL/cUL and TUV to the latest ITE standards, including UL/EN/IEC 62368-1, CSA 22.2 No. 62368-1.

The adapter complies with EMC and immunity standards including EN 55032, CISPR 32/FCC, VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11.

With a less than 92 per cent efficiency at full load, the series meets DoE Level VI and CoC Version 5 Tier 2 standards.

Using the power supply allows for early compliance to the new IEC 62368-1 hazard-based, performance-orientated standards, which will be replacing the current IEC 60950-1 safety standards on December 20 2020.

Trumpower provides medical and industrial grade AC/DC switching power supplies and DC/DC converters. Medical grade power supplies range from 4W to 1200W and its line of ITE grade AC/DC power supplies range from 3W to 1400W in wall mount, desktop, open frame, and ATX PC form factors.
