CUI has expanded its VOF series of compact, open-frame AC-DC power supplies with new 100W, 120W and 150W models.
This second generation of open-frame power supplies provides a number of improvements over the company’s previous offerings, including higher efficiency, improved no-load performance and a boost in power.
The power supplies can accommodate a wide universal input voltage of 90-277V AC from a 47-63Hz supply, offering compatibility with mains power worldwide.
The new VOF power supplies are available with a choice of output voltages: 5V, 12V, 15V, 24V, 36V and 48V.
All models include output-voltage adjustability of ±5%, set via an on-board potentiometer.
The VOF-100 is rated for operation at 100% load and across a temperature range of -20°C to 50°C with 6.7 cubic feet/minute of forced air cooling. This load must be de-rated by 50% for operation at 60°C. The VOF-120 and VOF-150 models operate with convection cooling at 100% load from -20°C to 40°C, also de-rating the load by 50% load at 60°C.
Operating at up to 90% efficiency, the new VOF series features no-load power consumption as low as 0.25W.
The VOF-150 model is equipped with active power factor correction. All models are packaged in industry standard footprints. The VOF-100 measures 4” x 2” x 1.32”, while the VOF-120 and VOF-150 models measure 5” x 3” x 1.32”.
