XP Power announced three new series of external/desktop power supplies that meet the latest level VI and CoC Tier 2 green standards. The single-output power supplies are ideal for customers requiring a low-power, external, 18, 24 or 36 W power source for their new designs that need to meet current legislation aimed at increasing energy efficiency and reducing no-load power consumption.
The VET18, VET24 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 0,075 W for the 6-36 W output power level. The VET series power supplies all feature a no-load input power below that level, thus meeting the new requirements. Less power is consumed when the end unit is off, or not connected to the power source.
In all three power ranges, output models of 12, 15, 18 and 24 V d.c. single outputs are available, these being the most common output voltages to suit most applications. Additionally, the VET18 series includes a 9 V d.c. model.
Able to operate over a wide temperature range of 0°C to +60°C with full power to +40°C (+45°C derating for VET36), the VET series will easily operate in most environments. 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 2,5 mm inner and 5,5 mm outer diameter ‘standard’ dimensions. The VET range will find favour with users in many industry areas including automation and process control, broadcast, fixed telecom, instrumentation, networking/datacom/computing, mobile comms and specialist equipment.
