SPX-21D
SPX Series Static Power Switching Unit (Automatic Transfer Switch)
Din Rail-mount
OVERVIEW
The new Ashe Series SPX-21D Static Power Transfer Switches are a
range of microcontroller based thyristorized AC power switching units.
The instrument is used as a watchdog for the AC mains power line in
industries. It accepts two single phase power feeders as input lines.
Depending upon the preset selections for load voltage and current
limits, the SPX-21D seamlessly switches one of the two input sources
to the output.
The Static Power-21D Switch provides a selection of one primary
feeder out of two input power feeders. Further, it monitors the voltage
and current continuously and sequentially displays these values on the
front panel digital display. The instrument has a membrane switchpad
on the front panel through which one may set all the parameters. An
active LED mimic indicates the status of the input and output signals.
The Ashe SPX-21D Power Switching unit has intelligent Auto-Recovery
facility – hence when power is restored, the instrument automatically
returns to the primary power feeder. It is offered in slim and
aesthetically designed enclosures of DIN Rail mount execution.
The design uses state of the art techniques in high speed bump-less
power switching, providing excellent voltage monitoring, high
efficiency and low power dissipation. It is offered in a wide range of
output voltages and power ratings. The Series SPX-21D units are
designed for continuous full load operation in tough industrial
environments, while ensuring the protection of the powered
equipment.
