AC-DC Power Supplies For Industrial Applications

The VCS series of chassis-mount single-output AC-DC power supplies from XP Power are aimed at cost-sensitive industrial applications. Extending the line-up of XP Power's V-Brand range of low-cost power supplies, the units are ideal for 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 per cent 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 0.5W the VCS family helps designers ensure their products comply with internationally recognised energy efficiency initiatives. The VCS series accommodates the full universal input range from 90-264VAC without de-rating, ideal if the end application is to be used worldwide.

It can provide full output power from -10C to +50C without de-rating, and with de-rating to +70C. Start-up is from -20C. 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.
