Purpose / Description
The TXS series is a 75 to 100 Amp, open frame, highly efficient, board mountable DC/DC converter.
The low voltage – high amperage supplies the next generation of microprocessors, gate arrays and
integrated circuits with reliable power. The TXS series features input undervoltage lockout, plus
overload and overtemperature protection and its input-output voltage combination is ideally suited for
Distributed Power Architectures (DPAs).
