The Z-Series of DC/DC converter modules Z-ZERIES has been specifically designed in response to the need for low voltage at moderate current levels supplied with the high efficiency and tight regulation dictated by modern digital processing applications. These converters are designed specifically for operation in radiation environments that are presented to commercial communication satellites operating in long term GEO and LEO orbits. They have been created to complement the spectrum of electrical and radiation performance available in the Advanced Analog ART2815T and M3G-Series converters. Requirements occurring in space vehicles  operating in Geostationary orbits, launch boosters, scientific space probes Z-ZERIES and similar applications requiring a low voltage, high efficiency converter with well characterized radiation hardness performance will be optimally satisfied by the Z-Series converters.

An additional benefit of the Z-Series Z-ZERIES is high power density. This is facilitated by utilizing the best features of chip and wire hybrid technology and surface mount fabrication techniques. The hybrid portion is fabricated in a facility fully qualified to MIL-PRF-38534 and processed to class K requirements. The standard processing adopted for the Z-Series module has been created to assure with margin the reliability required for space applications. Applicable generic lot qualification test data including radiation performance will be made available on request. Variations to the standard screening may be accommodated.
