Schneider Electric TBUX297102 / 5103 Uninterruptible Power Supply Module
SCADAPack 5103 uninterruptible power supply module with isolated 5 V and 24 V outputs and an integrated battery charger.
Product Overview
Isolated SCADAPack power with battery-backed operation
Schneider Electric TBUX297102 is the Model 5103 uninterruptible power supply module. It powers SCADAPack controllers and 5000-series I/O or modem modules through isolated 5 V and 24 V outputs.
A built-in charger supports a 12 V gelled-electrolyte battery. If main power is unavailable, the module operates from the battery to maintain controller and loop-powered instrumentation supply.
