(See wiring diagram for connection details.) The total combined load must be below 1200W at startup. Current sharing can be achieved with or without remote sense connected to the common load. V_SB outputs can be tied together for redundancy but total combined output power must not exceed 20W. The V_SB output has internal ORing MOSFET for additional redundancy / internal short protection. The current share pin 5 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 3 units can be paralleled together. Please consult your Murata sales representative if operation with more than three units in parallel is needed. www.murata-ps.com/support CPS_C1U-W-1200-48-Tx.B01 Page 4 of 5 C1U-W-1200-48-Tx Series AC/DC Front End Power Supply MECHANICAL DIMENSIONS Dimensions: 5.5 " x 14.2" x 1.67" [139.7mm x 361.2mm x 42.5mm] CONNECTORS Signal 16 pin connector details, Type: TE Connectivity (Tyco) 281281-1 Mating part 1658622-3 Pin Signal 1 AC_OK 2 P_GOOD 3 PS_ON 4 BLANK 5 I_SHARE 6 BLANK 7 SENSE+ 8 SENSE9 V_SB 10 V_SB 11 V_SB 12 V_SB 13 GND 14 GND 15 GND 16 GND 2-Pole terminal Block for AC Line and Neutral Stud on Chassis for earth + 48V Main Output GND Murata Power Solutions, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
