LPQ250
 

The LPQ250 series of enclosed AC-DC power supplies can be specified with end or top fan covers. With either fan cover, the power supplies provide up to 250 watts. They can also be ordered without a fan for applications which provide an alternative means of cooling. The LPQ250 has four outputs, one of which is floating and user-adjustable.
