SECTION 4
AC POWER SUPPLY (ACPS)
4.1
GENERAL DESCRIPTION
The ReFlex Power™ system includes an AC power supply rated at 875VA with
two output voltage ranges, 0-140VAC and 0-280VAC. There are two models
available; one with an output frequency range of 45-1200 Hz, and another with
an extended frequency range of 45-5000 Hz. This AC source 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 AC module can be set up to operate as a standalone asset, in
combinations of parallel, and in multi-phase groups to extend their voltage,
current, and power ratings.
The module operates as part of a remotely controlled system. They utilize 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
programming, read back, and configuration control. 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 lightweight and small size. The module is
housed in a three-width enclosure, 4.2" W x 6.75" H x 15" D, and is only 11.4 lb.
Mounting within the Mainframe is facilitated with chassis guides, backplane guide
pins, and front panel captive fasteners for securing the modules. The thermal
design features integral, variable-speed fans so that the cooling performance
scales with the complement of modules in the Mainframe, and their output
loading, minimizing the audible noise and airflow requirements.
The unique features of the ReFlex Power™ system for reconfigurability and
extensibility are made possible through the use of the latest in controls
