Figure 2-1 Power Supply Module (HVB4U, HVB8U, HVB12U)

The power supply module for the 4U, 8U, and 12U
chassis are the same as shown in the illustration
to the right for the HVB4U. The power supply
module converts the main input power to an
unregulated low voltage DC supply. There are two
versions of the power supply to provide 115 VAC
or 240 VAC 50 / 60 Hz. It is additionally possible to
power a VideoBloX chassis from a 18 to 24 VAC or
18 to 24 VDC supply. Power indications are visible
from the front of the chassis. The power supply is
equipped with the necessary protection and
filtering to ensure regulatory compliance. It is
possible to bring backup power into a chassis so
that operation is not affected by the failure of the
main input power supply. The power supply
module provides an unregulated DC output to the
backplane and each VideoBloX module is
equipped with independent voltage / current
regulation circuitry. The VideoBloX power supply
has adequate capacity to power all modules
within a chassis and also a limited number of
external control keyboards. The distance between
the chassis and the external control keyboard is
also a limiting factor.
A system reset push button is accessible from the
front panel after removal of a cover plate. The
power supply module also incorporates
communication drivers, used to interconnect
multiple subracks for assembly of large matrices.
