The D1U54-D-1200-12-HxxPC series are highly efficient 1200 watt, DC input front end modules with a 12V main output
and a choice of 3.3V or 5V (20W) standby rails. The power module is able to current share with up to eight (8) other
power modules of the same type operating in parallel or N+1 redundancy. The supplies may be
hot plugged, and include integral isolation devices.
The power modules are fully protected from overload and overvoltage and are able to auto-recover from
overtemperature faults. A Status LED is provided on the front panel and additional control and status reporting is
provided by hardware logic signals and via a PMBus™ digital interface.
A low profile sub 1U height enclosure provides an excellent power density of >28W/in
3
that is ideal for delivering reliable,
efficient power to servers; workstations; storage systems and other 12V distributed power systems, including direct
operation from intermediate bus converters.

For slow over-current events, a constant current will be
sustained for 1sec followed by a latch off that will reset
after 5secs. For hard (short circuit) events the output
will shutdown within 50ms and autorestart within
200ms. This cycle will be repeated 10 times after which
point the output will permanently latch off. The power
module will require reset by recycling the incoming DC

CURRENT SHARING NOTES
1. Main 12VDC Output: Analogue active share bus. The ISHARE bus (Pin B5 or D4) must be connected on all sharing modules.
It is not required that the SENSE signals are connected to the remote load for current share to operate correctly.
2. Up to eight (8) power modules can be connected in parallel (non-redundant) or N+1 configuration. The current share bus is analogue bi-directional (can
source or sink current from the ISHARE bus).
The voltage of the bus would measure approximately 8VDC for a single power module at 100% load; for two (2) modules sharing a common load the
ISHARE bus voltage would be approximately 4V for a perfect 50/50 current share scenario.
3. The VSB (Standby Output) output of the power module can also be connected in parallel; internal output isolation devices are provided however the
combined available power is limited to that available from a single power module (3.3V or 5V; 20W) irrespective of the number of modules connected in
