Output Overload Protection
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 constant-current mode.
Hot-Swap Capability
Output Fault Isolation
Remote Sense Lead Protection
Design Verification Testing (DVT) confirms that voltage excursions on the output buses resulting from insertion/extraction events do not exceed
the specified maximum of 10%. However, routing of power and signal lines in the mating backplane is critical to minimization of such excur-
sions. In addition, performance can be critically affected by load characteristics including resistance, negative resistance, and reactive com-
ponents. 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.
Outputs V1 & V2 are capable of compensating for >50mV of line drop. Unit automatically reverts to local sensing in the event that the sense
lines are opened for any reason. Unit is also protected against reversed or shorted sense leads.
STATUS & CONTROL SIGNALS & INDICATORS
Name
Description
Enable (EN#)
Short pin 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.
Output Inhibit (INH#)
Secondary referenced; active low, TTL compatible. Logic “0” or short circuit to output return inhibits all outputs.
Output Fault (FAL#)
Secondary referenced. Open collector signal denotes that one of the output voltages has fallen below the lower regulation limit.
Remote Sense (RS+, RS-)
Connection of the sense leads across the load at the desired point of regulation will compensate for voltage distribution drops up
to 50mV 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 V1 & V2.
Thermal Warning (DEG#)
Secondary referenced. Open collector denotes a thermal warning; nominally, 10ºC prior to thermal shutdown.
Fault Indicator LED
Power Present Indicator LED
Output Inhibit Indicator LED
IPMI Interface Option
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.
An amber LED will be illuminated when the output is inhibited.
An I2C interface board is available as a factory-installed option to provide an IPMI interface to the SMBus. Status functions
include output voltage and current levels as well as the DEG# warning. Output inhibit control can also be toggled via software
command. See application note ACAN-02 for the satellite controller specification, ACAN-03 for the firmware update procedure,
and ACAN-04 for the test procedure.
