GENERAL DESCRIPTION
The Fixed Power DC (FPDC) power supply of the ReFlex Power™ system
includes one model rated at 165W. It is part of a modular family of power assets
that integrate into the ReFlex Power™ Mainframe to provide a wide range of
features, functionality, and extensive configurability and adaptability.
The module operates as part of a remotely controlled system. It utilizes the
ReFlex Power™ Mainframe backplane for input power distribution and
control/communications interface. Through the ReFlex Power™ Controller
module, communications with the user host controller is established for
operation, configuration control and calibration. All connections to the user load
and discrete control signal interface are available on the module front panels.
The module utilizes high-frequency power conversion for high efficiency to
maximize power density and realize light weight and small size. The module is
housed in a single-width enclosure, 1.4” W x 6.75” H x 15” D, and is only 4.7 lb.
Mounting within the Mainframe is facilitated with chassis guides, backplane guide
pins, and front panel captive fasteners for securing the module. The thermal
design features integral, variable-speed fans so that the cooling performance
scales with its output loading, minimizing the audible noise and airflow
requirements.
The unique features of the ReFlex Power™ system of reconfigurability and
extensibility are made possible through the use of the latest in controls
technology. An FPGA-based implementation uses VHDL, embedded processor
cores for firmware-based systems control, and ArcNet
®
inter-module
communication and LAN system communications.
