temporary or intermittent condition. Furthermore, all modules located
within the chassis rack are hot-swappable, so that it is not necessary to
power-down the rack when removing or replacing modules.
Rather than utilizing a switching-mode or linear DC power supply
for providing the operating power to the rack as employed by most
competing designs, the IFS Model R3 Chassis Rack uses a
simple under stressed step-down power transformer,
and all rectification, filtering, and regulation is performed
within each rack mounted module. The use of a step-down
power transformer for the power supply unit results in a
significantly higher MTBF than any switching-mode or linear
DC power supply can provide, as there are no semiconductors,
electrolytic capacitors, etc., to degrade the reliability of the supply. In
addition, the high-reliability transformer power supply and current limiting
built into each module, eliminates the necessity of providing redundant
power supplies within the chassis rack, as the overall system reliability is
still much higher (and less costly) than can be provided with a redundant
power supply design approach.

QUALITY DESIGN
The design approach employed by IFS for equipment mounted
within the model R3 Chassis Rack Unit with Integral 115/230 VAC
Power Supply, provides for the elimination of a single-point failure
in the event of a major fault within any module located within the
chassis rack. This is accomplished through the use of automatic
electronic current limiting within each rack-mountable module,
rather than to provide the current limiting within the power supply
unit which supports the power requirements for equipment located
within the rack. In nearly all competing designs, a major fault within
a module, located within the chassis rack, results in the power supply
unit going into a current limiting condition, and as a result, all of the
modules located within the rack shut down. The R3 Rack design
employed by IFS eliminates this possibility, as only the faulty
module shuts down, and the operation of the other devices within the
rack continues unimpaired. This automatic current limiting
feature is also self-resetting, should the fault or overload be of a
