Description

MVAC400-48AFD
MVAC400-12AFR
Main Output: Current share is achieved using the droop method. Nominal output voltage is achieved at 50% load and output voltage increases/drops at a rate of:
• 30mv per amp for the 12V output
• 120mV per amp for the 24V output
• 500mV per amp for the 50V output.
Startup of parallel power supplies is not internally synchronized. If more than 400W combined power is needed, start-up synchronization must be 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, use the AFR model or if the AFD model is selected please contact Murata sales for external ORing FET board or external ORing
FET reference circuit design (also see Applications Note ACAN-42).
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 com load must not exceed 12W, external ORing devices must be used.
