Split Temporal Mode of Operation
5.3 Split Temporal Mode of Operation
In this application, the power supply has been set as a master with two synchronized and two
nonsynchronized outputs as determined by the Split Temporal mode feature. Control Input #1
(TB4, Terminals 3 & 4) is connected to an addressable control module which will cause the
synchronized power supply output circuits 1 & 2 to turn on. Control Input #2 (TB4, Terminals 7 &
8) is connected to an FACP Notification Appliance Circuit which is used to activate the power
supply’s temporal output circuits 3 & 4.
