(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 20W. The +VSB output has internal ORing MOSFET for addi- tional redundancy / internal short protection. The current share pin B3 is a connection between the two 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 4 units can be paralleled together. Please consult your Murata sales representative if operation with more than 4 units in parallel is needed. www.murata-ps.com/support D1U3CS-W-850-12-HxxC.B02 Page 5 of 6 D1U3CS-W-850-12-HxxC Series 81mm 1U Front End AC-DC Power Supply Converter MECHANICAL DIMENSIONS 75.00 2.953 Airflow Back to Front Airflow Front to Back Power Supply Power Supply FRONT BACK 75.00 2.953 275.50 ±0.70 7.0 10.846 ±0.028 0.276 279.40 ±0.50 11.000 ±0.020 75.00 83.80 ±0.70 15.51 ±0.80 2.953 0.611 ±0.031 3.299 ±0.028 75.00 2.953 AC input connector: IEC 320-C14 Dimensions: 3.20" x 11.00" x 1.571" [81.3mm x 279.4mm x 39.9mm] OPTIONAL ACCESSORIES Description Part Number 12V D1U3CS Output Connector Card D1U3CS-12-CONC APPLICATION NOTES Document Number Description Link ACAN-41 D1U3CS Output Connector Card www.murata-ps.com/data/apnotes/acan-41.pdf ACAN-43 D1U3CS-x Communication Protocol www.murata-ps.com/data/apnotes/acan-43.pdf This product is subject to the following operating requirements Murata Power Solutions, Inc. and the Life and Safety Critical Application Sales Policy: 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
