XP Power has developed four external power supply series that enable products to meet the new EU and US environmental and energy efficiency regulations which come into force this year. The VEC40, VEC50, VEC65 and VES90 series of external AC/DC power supplies all comply with the new DoE level VI (US) and CoC Tier 2 (EU) regulations.

CoC Tier 2 came into force on 1st January 2016 while DoE Level VI takes effect on 10th February 2016. These requirements reduce the no-load power to less than 0.15W (50-250W; 0.075W for 1-49W) and push the market towards a flatter efficiency curve, with efficiency readings now required at 10, 25, 50, 75 and 100% of load.

With single output models created to deliver 12, 15, 19, 24 and 48VDC, the external supplies are suited to a wide range of industry segments, and especially to portable devices and applications that require the power supply to be external from the end product.

The supplies, which measure 116.3x52.4x3.13mm for the VEC series and 139.0x58.0x31.0mm for the VES series, come with a common IEC320-C14 input connector, with VEC series supplies also available with an optional IEC320-C6. The VEC models additionally are approved as limited power sources, which reduces the risk of shock if incorrectly installed.

The VEC40 and VEC50 have an operating temperature range from 0 to +65°C, derating from 45°C. The VEC65 and VES90 have an operating temperature range from 0 to +60°C with derating from 40°C. All models have CCC (China Compulsory Certification) as well as ITE 60950-1 safety approvals and meet Class B limits for both conducted and radiated EMC noise.

The VEC40, VEC50, VEC65 and VES90 series are available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power.
