Nominal output voltage is achieved at 50% load and output voltage increases/ drops at a rate of: 48mv per amp for 12V output 192mV per amp for 24V output MVAC250-12AFD 800mV per amp for 50V output. Startup of parallel power supplies is not internally synchronized. If more than 250W combined power is needed, start-up synchronization must be MVAC250-24AFD provided by using a common PS ON signal. To account for 10% full load current sharing accuracy and the reduction in full load output voltage due to droop, available output power must be derated by 15% when units are operated in parallel. Current sharing can be achieved with or without remote sense connected to the common load. If ORing protection is desired, please contact Murata sales for external ORing FET board or external MVAC250-48AFD ORing FET reference circuit design. Aux (V3) output can be tied together for redundancy but total combined output power must not exceed 10W, external ORing devices must be used. Fan (V2) can be tied together for redundancy but total combined output power must not exceed 12W, external ORing diodes can be used. www.murata-ps.com/support MVAC250.C03 Page 2 of 9
