D1U86-D-1600-12-HxxDC Series
86mm 1U Front End DC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U86P-D-1600-12-HxxDC series are highly efficient 1600 watt, DC input front end supplies with a
12V main output and a 12V (30W) standby. They have 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
logic and PMBus monitoring and control. Their low profile 1U package and >38.6W/cubic inch power
density make them ideal for delivering reliable, efficient power to servers, workstations, storage systems
and other 12V distributed power systems.

Input Fuse
Weight
Power Supply has internal 60A/170VDC fast blow fuse on the DC line input
1.108kg (2.44lbs)
The load current of 100% refers to each power module max load connected in an N+1 configuration; therefore the total load will be “N” x 100% load of each module. The share accuracy of ±5% is a fixed
percentage irrespective of the total loading and number of units connected in parallel.
PROTECTION CHARACTERISTICS

Parameter
Conditions
Min.
An OTP warning will be issued via the PMBus interface when the air inlet exceeds 70°C;
however the power module shall not shut down until critical internal hotspot temperatures are exceeded.
The unit will shut down when internal hot spot exceed the derating guide lines and autoOvertemperature (hotspots) matically recovers when the unit is cooled down. The unit will shut down due to hot spot
at ambient temperature between 55°C-60°C with main 12V at full load.
Overvoltage
Latching
For overloads (slow) over current events a 147A nominal constant current will be sustained until the output voltage drops below 3VDC. At this point the unit shall shut down
after a 1sec period and remain in that condition for 10secs. The cycle will then repeat.
Overcurrent
For severe (short circuit) over current events the unit shall shut down within 1ms and
remain in this condition for 200ms before attempting a re-start. the unit shall attempt
10 shutdown/re-start cycles before permanently latching off. It will then be necessary to
either recycle the DC input or toggle the PSON# input.

PSON#
Low = main output on; PSON# can be permanently tied to GND within the host system.
Short pin pulled down on p/s; pulled up to either 3.3V or 12V (max) in the host system. For 3.3V use a 5.11KΩ resistor; for 12V
use a 21KΩ resistor.
Open drain PMBus signal; can be left open if not used.
PMBus Address; ADDR can be grounded or left open if not used. If grounded, the address will be 000, if it is open, the default

CURRENT SHARING NOTES
Main Output: Current share is achieved using the droop method. Nominal output voltage (12.20V) is achieved at 50% load and output voltage changes at a rate of
3.10mv per amp. Startup of parallel power supplies is not internally synchronized. If more than 1600W combined power is needed, start-up synchronization must
be provided by using a common PS_ON signal. To account for ±5% full load current sharing accuracy and the reduction in full load output voltage due to droop,
available output power must be derated by 10% when units are operated in parallel. Internal ORing FETs are provided.
Standby output can be tied together for redundancy but total combined output power must not exceed 30W; Internal MOSFET ORing devices are used.
