D1U54P-W-1200-12-HxxPC Series
54mm 1U Front End AC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U54P-W-1200-12-HxxPC series are 80 PLUS® Platinum efficiency 1200 watt, power factor corrected front end
supplies with a 12V main output and a 3.3V (3A) or 5V (3A) standby. They have active current sharing and up to 8
supplies may be operated in parallel. The supplies may be hot plugged, they recover from overtemperature faults, and
have status LEDs on their front panel in addition to logic and PMBus™ status signals. Their low profile 1U package
and >28W/cubic inch power density make them ideal for delivering reliable, efficient power to servers, workstations,
storage systems and other 12V distributed power systems.

Description
Interface Details
Output
The signal output is driven high when input source is available and within acceptable
limits. The output is driven low to indicate loss of input power.
There is a minimum of 1ms pre-warning time before the signal is driven low prior
to the PWR_OK signal going low. The power supply must ensure that this interface
signal provides accurate status when AC power is lost.
Pulled up internally via 10K to VDD.4
A logic high >2.0Vdc
A logic low <0.8Vdc
Driven low by internal CMOS buffer (open drain output).
Output
The signal is asserted, driven high, by the power supply to indicate that all outputs
are valid. If any of the outputs fail then this output will be hi-Z or driven low. The
output is driven low to indicate that the Main output is outside of lower limit of
regulation (11.4Vdc).
Pulled up internally via 10K to VDD.4
A logic high >2.0Vdc
A logic low <0.8Vdc
Driven low by internal CMOS buffer (open drain output).
SMB_ALERT
(FAULT/
WARNING)
Output
The signal output is driven low to indicate that the power supply has detected a
warning or fault and is intended to alert the system. This output must be driven high
when the power is operating correctly (within specified limits).
The signal will revert to a high level when the warning/fault stimulus (that caused
the alert) is removed.
Pulled up internally via 10K to VDD.4
A logic high >2.0Vdc
A logic low <0.8Vdc
Driven low by internal CMOS buffer (open drain output).
PRESENT_L
(Power Supply
Absent)
Output
The signal is used to detect the presence (installed) of a PSU by the host system. The
signal is connected to PSU logic SGND within the power module.
Passive connection to +VSB_Return.
A logic low <0.8Vdc
Input
This signal is pulled up internally to the internal housekeeping supply (within the
power supply). The power supply main 12Vdc output will be enabled when this signal
is pulled low to +VSB_Return. Pulled up internally via 10K to VDD.4
In the low state the signal input shall not source more than 1mA of current. The
12Vdc output will be disabled when the input is driven higher than 2.4V, or open
circuited. Cycling this signal shall clear latched fault conditions.
PSKILL
Input
This signal is used during hot swap to disable the main output during hot swap
extraction. The input is pulled up internally to the internal housekeeping supply
(within the power supply).
The signal is provided on a short (lagging pin) and should be connected to +VSB_
Return.
A logic high >2.0Vdc
APS (Address
Select)
Input
An analog input that is used to set the address of the internal slave devices (EEPROM
and microprocessor) used for digital communications.
Connection of a suitable resistor to +VSB_Return, in conjunction with an internal
resistor divider chain, will configure the required address.
DC voltage between the limits of 0 and VDD.4
Both
A serial clock line compatible with PMBusTM Power Systems Management Protocol
Part 1 – General Requirements Rev 1.1.
No additional internal capacitance is added that would affect the speed of the bus.
The signal is provided with a series isolator device to disconnect the internal power
supply bus in the event that the power module is unpowered.
VIL is 0.8V maximum
VOL is 0.4V maximum when sinking 3mA
VIH is 2.1V minimum

STATUS AND CONTROL SIGNALS
V1_SENSE
V1SENSE_RTN
ISHARE
4
Input
Remote sense connections intended to be connected at and sense the voltage at the
point of load.
The voltage sense will interact with the internal module regulation loop to
compensate for voltage drops due to connection resistance between the output
connector and the load.
If remote sense compensation is not required then the voltage can be configured for
local sense by:
V1_SENSE directly connected to power blades 6 to 10 (inclusive)
V1_SENSE_RTN directly connected to power blades 1 to 5 (inclusive)
Compensation for up to 0.12Vdc total connection drop
(output and return connections).
Bi-Directional
Analogue
Bus
The current sharing signal is connected between sharing units (forming an ISHARE
bus). It is an input and/or an output (bi-directional analog bus) as the voltage on the
line controls the current share between sharing units. A power supply will respond to
a change in this voltage but a power supply can also change the voltage depending
on the load drawn from it. On a single unit the voltage on the pin (and the common
ISHARE bus would read 8VDC at 100% load (module capability). For two identical
units sharing the same 100% load this would read 4VDC for perfect current sharing
(i.e. 50% module load capability per unit).
Analogue voltage:
+8V maximum; 10K to +12V_RTN
VDD is an internal voltage rail derived from VSB and an internal housekeeping rail (“diode ORed”) and is compatible with the voltage tolerances of VSB).

CURRENT SHARING NOTES
Main Output: Current sharing is achieved using the active current share method. (See wiring diagram for connection details.)
Current sharing can be achieved with or without remote sense connected to the common load.
+VSB outputs can be tied together for redundancy but total combined output power must not exceed the rated standby power. The +VSB output has internal ORing MOSFET for
additional redundancy / internal short protection.
The current share pin B5 (or D4 for alternate pin out model) is a connection between the units. It is input and/or output as the voltage on the line controls the current share. A power
supply will respond to a change in this voltage but a power supply can also change the voltage depending on the load drawn from it. On a single unit this would read 8V at 100%
load. For two units sharing load then this should read 4V for perfect current sharing.
Up to 8 units can be paralleled together. Please consult your Murata sales representative if operation with more than 8 units in parallel is needed.
