CURRENT SHARING OPTION PQC250-XX-DXX
Model Number Description
Main Output current share is achieved using the droop method. Nominal output voltage is achieved at 50% load and output voltage increases/decreases approximately
PQC250-XX-Dxx
3% of nominal voltage. This regulation window does not include the additional tolerance due to line, temperature, long term stability etc.
Refer to
Startup of parallel power supplies is not internally synchronized. If more than 250W combined power is needed, start-up synchronization must be provided by system using
ACAN-78 f
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
or additional
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.
details
ORing protection is available on the PQC250-xxDRT models (see Application notes, ACAN-78 for additional details); Aux (V2) output can be tied together for redundancy but
total combined output power must not exceed 2.5W, external ORing devices are recommended to preserve redundancy.
