Railway product and systems development is constantly evolving. When it comes to the end customer’s expectations, many different but technically competing aspects converge: comfort, efficiency, environment, and safety amongst others.
Electrical and mechanical components for the railway industry need to provide reliable and safe operations while running under wide temperature fluctuations, condensation, electromagnetic interference, and shock and vibrations. Under these circumstances, nothing can be left to chance.
Premium PSU has been providing reliable power supply solutions for over four decades and currently carries the largest DC/AC inverter portfolio in the market along with a wide range of DC/DC converters. Solutions that go from 60W to 50kW and comply with the most relevant standards (EN45545-2, EN50155, EN61373, ISO, DIN, IEEE, etc.), which are developed and manufactured in Barcelona.
Innovation and state-of-the-art technology set Premium PSU apart. Working with the largest train and locomotive manufacturers and being involved in projects all around the world has given Premium PSU a comprehensive experience in the field of rolling stock and extensive industrial know-how. Solutions can be found in and out of the convoy, where a multitude of Premium PSU’s devices work to guarantee performance, safety, and comfort.
Premium’s DC/DC converters and DC/AC inverters, make possible the operation of elements and services that are essential for passengers. Systems such as those located in the doors, the bistro bar wagon services or the integrated toiled modules are made of equipment that must work reliably during the trip. Providing power to the traction system and all other systems on the train, including heating and ventilation, lighting, public information displays, on-board video system management or activating running lights and windscreen wipers are a few of the many applications of Premium’s power supplies in rolling stock.
