Part Number: SUB-5151-00 ## Overview A rugged DC/DC power supply daughter card providing MIL-STD-704/1275 compliant power conditioning from a nominal 18-36 VDC input. It is designed to operate within a specific small form factor mission computer chassis, interfacing directly with the system mainboard via a high-density board-to-board connector. It delivers multiple regulated DC output rails for internal subsystems and features transient, spike, and surge protection. The card is intended for military, aerospace, and industrial C4ISR applications requiring reliable power from vehicle, aircraft, or battery sources. ## Function Provides regulated and isolated DC power conversion and distribution within rugged embedded computing systems, specifically designed as a power supply daughter card to interface with the DuraCOR-820 hardware platform. Supports extended temperature range and high shock/vibration environments typical of military and aerospace applications, ensures compliance with MIL-STD-1275/704 power input standards, and incorporates EMI/EMC filtering per MIL-STD-461F to maintain system electromagnetic compatibility. Enables remote power on/off control and protects against voltage surges to maintain system reliability and operational continuity. ## Platform Designed as a power supply daughter card for integration within rugged embedded computing systems, this module operates specifically in the DuraCOR-820 hardware platform, providing regulated DC/DC power conversion. It supports harsh environments including extended temperature ranges (-40°C to +85°C), high shock, and vibration conditions typical in military and aerospace applications. The card interfaces electrically and physically via a daughter card connector facilitating power delivery and isolation compliant with MIL-STD-1275 and MIL-STD-704 standards, and includes EMI/EMC filtering to maintain system signal integrity without additional external conditioning components. ## Application Provides regulated power distribution and voltage conversion for embedded computing modules in rugged military and aerospace environments. Designed for high-reliability applications requiring operation in extreme temperatures, shock, vibration, and electromagnetic interference conditions. Supports critical defense systems including unmanned vehicles, radar processing, electronic warfare platforms, and mission-critical data acquisition systems where power supply failure is not acceptable. ## Accessories Requires the DuraCOR-820 mainboard or embedded computer chassis for installation. Connects via a dedicated backplane interface specific to the DuraCOR-820 system. Typically includes a standard power connector compatible with Curtiss-Wright's ruggedized DC/DC power inputs. No separate external power supply needed; interfaces electrically to the host's power system. Designed to supply regulated auxiliary power to the DuraCOR-820 system modules. Connector types are proprietary high-density board-to-board connectors matching the host's backplane form factor. No additional cables or adapters documented. ## Interface CompactPCI Serial interface, 12V and 5V output connectors, Eurocard format, 3U size, backplane compatible with DuraCOR-820. ## Images - - - -
