'Green mode' low-cost, chassis mount industrial power supplies

01 October 2010

XP Power has introduced the VCS series of chassis mount, single output ac dc power supplies aimed at cost sensitive industrial applications. Extending the XP Power V Brand range of low cost power supplies, these units suit applications that require an enclosed power supply with screw terminals.

The series comprises 50, 70 and 100W models and are available with +5, +12, +15, +24 or +48 Vdc outputs. A user accessible voltage trim control provides a +/- 10% adjustment of the output voltage allowing use of non-standard voltages or providing compensation for cable losses. These high efficiency 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, and can provide full output power from -10 degrees C to +50 degrees C without de-rating (to +70 degrees C with de-rating). Start-up is from -20 degrees 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.
