The VET18, VET24, VET30 and VET36 ranges feature a high average efficiency of up to 87% typical, measured at 25, 50, 75 and 100% load conditions. Accordingly, they meet the requirements from the Department of Energy (DoE) in the US and the Code of Conduct (CoC) Tier 2 in the EU. These standards set limits for average energy efficiency and no load power consumption. The new requirement lowers the no load power to less than 0.075W for the 6-36W output power level. The VET series power supplies all feature a no load input power of <0.075W. Less power is consumed when the end unit is off, or not connected to the power source.
In all four VET series power ranges, output models of 12, 15, 18 and 24 VDC single outputs are available, these being the most common output voltages to suit most applications. Additionally, the VET18 series includes a 9 VDC model.
Able to operate over 0 to +60 degrees C with full power to +40C (+45 degrees C derating for VET36), all models have ITE 60950-1 safety approval and meet Class B limits for both conducted and radiated emissions. They form part of XP Power’s low cost V-brand series, offering a less expensive option for cost sensitive applications. The desktop power supplies feature an IEC input connector. An output cable is fitted with a barrel jack having 2.5mm inner and 5.5mm outer diameter ‘standard’ dimensions.
The units are available from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.
