Phoenix Contact's new Quint Diode power supplies are designed for redundant applications that require isolation and N+1 redundancy. Versions are available for use in 12-24V DC and 48 V DC operations. The power supplies' housings are made of extruded aluminum for improved cooling and longer service life. This decreases heat load in cabinets. The Quint Diodes use MOSFETs, rather than Schottky or silicon diodes used in most redundant power supplies. These MOSFETs are up to 70% more efficient than standard diode components. This limits the effect of a diode module on the load of the power supplies. The Quint Diodes carry UL 508 Listing as well as Class I, Division 2 Listing, making them well-suited for installation in critical process industry applications, http://www.phoenixcontact.com/usa_home.htm, 800-322-3225, e-mail firstname.lastname@example.org.
