Description
Short pin (#27) on connector will enable the outputs when the mating pin is grounded. Supply will not power up until this pin is engaged to
its mate in the backplane. Unit output will be inhibited as pin is disengaged from the mating connector.
Secondary referenced; active low, TTL compatible. Logic “0” or short circuit to output return inhibits all outputs.
Secondary referenced. Open collector signal denotes that one of the output voltages has fallen below the lower regulation limit.
Connection of the sense leads across the load at the desired point of regulation will compensate for voltage distribution drops up to 300mV
between the output terminals of the power supply and the point of connection. The unit reverts to local sensing if the sense lines are opened
for any reason. The output is protected against shorted or open leads. Applies to outputs V-V3.
Secondary referenced; TTL compatible. Open collector denotes a thermal warning; nominally, 0ºC prior to thermal shutdown.
An LED will illuminate red if the output voltages are not within specification, coincident with assertion of the FAL# signal.
A green LED will be illuminated when the input voltage is present and above the minimum requirement.

Conditions/Response
Outputs are individually protected against overloads and indefinite short circuit with automatic recovery upon removal of the
fault condition. Overload response for all outputs is hiccup mode.
Design Verification Testing (DVT) confirms that voltage excursions on the output buses resulting from insertion/extraction events
do not exceed the specified maximum of 8%. However, routing of power and signal lines in the mating backplane is critical to
minimization of such excursions. In addition, performance can be critically affected by load characteristics including resistance,
negative resistance, and reactive components. While the control loop responses have been designed for optimum hot-swap
performance over a wide range of characteristics, there may be instances where the voltage excursions exceed published
specifications. In such cases, the control loop responses can be modified to perform optimally.
Output isolation devices are present in all outputs to isolate faults within a failed power supply.
