The 90 Watt Power Supply Module is a rack-mounted unit that plugs directly into a 48-pin backplanemounted connector in the leftmost slot in the rack. It provides +5 volt, +12 volt and -12 volt power, and logic level sequencing signals to the backplane. This power supply can be used either in a single rack application, or can also be used to provide power to a second rack if the total load is within the supply rating. Interconnection to the second rack is through a prewired cable (IC697CBL700). The power supply output will ride through a 10 msec total loss of input power at full load. Protection is provided for overcurrent and overvoltage fault conditions.
