(see wiring diagram section for connection deta ils.) the total combined load must be below 400w at startup. startup of parallel power supplies is not internally synchronized. it is recommended that the paralleled pow er supplies be turned on at the same time (with their pson_l signals). current sharing can be achieved with or without remote sense connected to the common load. 5vsb output: 5vsb outputs can be tied together for redundancy but total combined output power must not exceed 15w. the 5vsb o utput has internal oring mosfet for additional redundancy / internal short protection. up to four units can be paralleled together. outputs of ac input units (d1u2-w-400) and dc input units (d1u2-d-400) can be par alleled together. please consult your murata sales representative if operation with more than four units in parallel is needed. dc out return +remote sense -remote sense +dc out d5 p5-p8 p1-p4 d4 - dotted lines show optional remote sense connections. optional remote sense lines can be attached to a load that is a distance away from the power supply to improve regulation at the load. d1u2 12v load a2 b2, b3, c2-c5, d2, e2, e5 a4, a5, b4, b5 close switch (or fet, bjt, or wire) to turn on +dc out +5v logic circuitry 5vsb pson_l rtn a3 pskill_l d1u2 d5 p5-p8 p1-p4 d4 a4, a5, b4, b5 a2 b2, b3, c2-c5, d2, e2, e5 a3 pson_l pskill_l d3 12ls d3 rtn +dc out dc out return -remote sense 12ls 5vsb +remote sense
