Product Summary
The LPQ250 AC-DC Power supplies can be specified with end or top fan covers. With either fan cover, the series gives up to 250W. The power supply can be ordered without a fan for requirements where external fan cooling is provided. The LPQ250 has 4 outputs, with the the fourth being an adjustable floating output.
