AC (100–125 Vac) and DC (12 and 24 Vdc) cooling fans protect electronic components by keeping them at optimal operating temperature to prevent harmful thermal variances and premature failure. While AC fans provide constant flow, DC fans can run at variable speeds. Offered 5 sizes from 40 x 40 mm to 120 x 120 mm, fans feature thermoplastic (DC) and die-cast aluminum (AC) impellers and frames, ball bearings, and 11.8 in. wire leads. Locked rotor protection is standard.
