The SBP-C14PS1 integral 115/230 VAC power supply for the SBP-C14 card cage provides for the elimination of a single-point failure in the event of a major fault within any module located within the SBP-C14 chassis rack, through the use of automatic electronic current limiting within each rack-mountable module.

In the SBP-C14PS1 design only the faulty module shuts down, and the operation of the other modules within the rack continue unimpaired. This automatic current limiting feature is also self-resetting, should the fault or overload be of a temporary or intermittent condition.
