Redefining the sources of power

Railway and Industrial Power Architectures

Simplifying your future


DC input buses

Railway and Transportation power supplies have always been subjected to stringent requirements including transients, energetic spikes and hold-up specifications. Traditionally, the majority of these power supplies have been developed specifically with discrete components.

With the introduction of modular systems, the use of standard DC/DC modules has gained importance in the design of complex power supplies. The standard input voltages in rail applications are 24, 36, 48, 72 or 110Vdc as in signaling applications.The 24Vdc is a variation described in the widely used EN50155 standard. Fast and energetic spikes are of primary importance and need to be handled with sufficient protection. The power requirements generally range from 4W up to 200W per board.

AC input buses

Industrial applications cover an extremely wide spectrum of applications from low requirements in automation robotics and test equipment up to the stringent constraints of transients and EMI in power plant and electricity distribution systems.

EMI requirements are described in the EN55022 standards with 2 levels: class A for Industrial environment and class B for Domestic environment. Susceptibility, covering fast transient, repetitive surge, and discharge
are all of primary importance and are described in the EN61000 standards.
