First Claim
1. A power supply adapted to be driven by a primary power source to produce an output voltage, comprising:
- a case having an air inlet and an air outlet;
converter means mounted in said case and adapted to be connected to said primary power source for producing said output voltage;
a fan mounted in said case between said air inlet and said air outlet for providing a separated pair of airflows downstream and upstream of said fan, said pair of airflows passing across different portions of said converter means; and
a controller operatively coupled to said fan and said converter means for powering said fan in response to output from said converter means exceeding a predetermined amount.

Abstract
A power supply adapted to be driven by a primary power source to produce an output voltage. The supply has a case with a bottom wall, an air inlet, an air outlet, and an enclosed chamber bordered by the bottom wall, the air inlet and the air outlet. The bottom is adapted to rest on a horizontal surface to define an upward direction within the case. The air inlet is operable to deliver air into the case along an incoming passageway having components directed inwardly and upwardly to prevent liquid that falls atop the case from intruding into the case. A power converter mounted in the case is adapted to be connected to the primary power source for producing the output voltage. The power supply also has a fan mounted in the case between the air inlet and the air outlet for providing a separated pair of airflows downstream and upstream of the fan. The pair of airflows pass across different portions of the power converter. The power supply also has a principal bulwark mounted in the case for (a) dividing the chamber, (b) supporting the fan, and (c) impeding bypassing of the fan.
