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 116.3×52.4×3.13mm for the VEC series and 139.0×58.0x31.0mm 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.
