PRODent Model Outputs are individually protected against overloads and indefinite short circuit with automatic recovery upon removal of the fault condition.
BSOLETfEor Replacem Design Verification Testing (DVT) confirms that voltage excursions on the output buses resulting from insertion/extraction events do not exceed the
specified maximum of 5%. However, routing of power and signal lines in the mating backplane is critical to minimization of such excursions. In
OContact Factory 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.
STATUS & CONTROL SIGNALS & INDICATORS
Name
Description
Hot-Swap Enable
Short pin on connector will enable the outputs when the mating pin is tied to DC GND. 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
Secondary referenced; active low, TTL compatible. Logic “0” or short circuit to DC GND inhibits all outputs.
DC Good
Secondary referenced. Open collector signal with an internal 2.2k pull-up resistor is connected to the +5V output. TTL signal will transition
high when all outputs are between 90% and 110% of their nominal voltage.
Remote Sense
Connection of the sense leads across the load at the desired point of regulation will compensate for voltage distribution drops up to 700mV
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 all outputs.
Fan Alarm
Secondary referenced; TTL compatible; active low. Signal transitions to a Logic 0 denotes a thermal warning.
Power Present Indicator LED
A green LED will be illuminated when the input voltage is present and above the minimum requirement.
DC Good Indicator LED
A green LED will be illuminated when the output voltages are within 90-110% of specification, coincident with assertion of the DC Good signal.
This LED will be extinguished if any of the output voltages is outside of this range.
Fan Good Indicator LED
A green LED will be illuminated when the fan is operational, coincident with de-assertion of the Fan Alarm signal. This LED will be extinguished
in the event of a fan failure.
Sync Start
A power supply generated signal used to simultaneously start power supplies connected in parallel when the load on any output exceeds a
single power supply’s capacity for that output. These pins must be bused together at the backplane in parallel/redundant applications (N+n)
when N>1. In simple redundant (1+1) or non-parallel applications (1+0), the pin can be ignored.
Power Supply Present
This pin presents a DC ground signal to the mating pin in the backplane. It is intended to be used by the system to detect the presence of a
power supply when the supply is mated into an available position.
