XP Power has announced the VCS series of chassis mount single output AC-DC power supplies aimed at cost sensitive industrial applications. Extending the line-up of XP Power's V-Brand range of low cost power supplies, these units suit applications that require an enclosed power supply with screw terminals. The series comprises 50W, 70W and 100W models and are available with +5, +12, +15, +24 or +48VDC outputs. A user accessible voltage trim control provides a ±10% adjustment of the output voltage allowing for the use of non-standard voltages or to compensate for cable losses. These highly efficient convection cooled units require no additional heat sinking or forced airflow saving space and additional costs. Also, having a no-load power consumption of less than 0.5 W the VCS family helps designers ensure their products comply with internationally recognised energy efficiency initiatives. Unlike some competitor products, the VCS series accommodates the full universal input range from 90 - 264VAC without derating, ideal if the end application is to be used worldwide. The VCS series can provide full output power from -10°C to +50°C without derating, and with derating to +70°C. Start-up is from -20°C. The range meets the UL60950-1 / EN60950-1 safety specifications for IT, commercial and industrial equipment. In addition, the units comply with EN550022 level B standard for both conducted and radiated emissions without the need for additional filtering components. Overvoltage, overload and short-circuit protection features are included as standard across the whole range. The VCS family is available from Farnell or direct from XP Power. www.xppower.com
