Master-Slave Series Overview
Background
When connecting PSU power supplies in series,
up to 2 units can be used in series and all units
must be of the same model. When operated in
series, the power supplies can be used to
increase the voltage output or setup the power
supplies to output both positive and negative
polarities. Unlike with the parallel operation,
the series operation does not require any
special configuration as each power supply is
operated and controlled individually.
When the units are used in series, a number of
precautions and limitations apply. Please read
this overview before operating the power
supplies in series.
