The APP is a portable non-standby power supply used to provide conditioned AC power to the load when the main power supply is being serviced. Used in conjunction with the “Alternate” connector and the “ALT/ON” switch located on the enclosure’s service power inserter, power can be transferred from the main power module to the APP without interrupting the connected load. The APP90S has an internal tap that allows the unit to be set for 90/75/60Vac applications.
