D1U3CS-W-1300F-12-Hx4EC Series
81mm Front End AC-DC Power Converter
PRODUCT OVERVIEW
The D1U3CS-W-1300F-12-Hx4EC are high efficiency 1300W power factor corrected front end supplies with a 12V main
output and a 5V or 3.3V (20W) standby. Active current sharing is provided to allow up to eight (8) supplies to be operated
in parallel. 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. Status LEDS are 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 a power density of >23W/in3 that is ideal for delivering reliable, efficient
power to servers, workstations, storage systems and other 12V distributed power systems.

CURRENT SHARING NOTES
1. Main 12VDC Output: Analogue active share bus. The ISHARE bus (Pin B3) 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 8VDC for a single power module at 100% load; for two (2) modules sharing a common load the ISHARE bus voltage would be 4V for a perfect 50/50 current share scenario.
3. VSTANDBY output power modules can also be connected in parallel and have internal output isolation devices; 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 parallel.
