📋 Tender Overview
Over the last few months both Delta and P-Duke have increased their product range of rail specific products all of which conform to the industry standard EN50155. All of these products have been specially designed to meet the harsh conditions found in the rail environment. With these including heat frost dust or vibration our range of dcdc converters are up to the exceptional challenge.What are DCDC converters used for in Rail applicationsEngineers use DCDC converters to convert battery power to stepdown to lower voltages rolling stock uses a DC power distribution system for operation of control circuity be that in the actual driver cab or to operate lights doors customer toilets and passenger information systems.Typical rail applications requiring DC DC ConvertersRailway rolling stockOn board peripheral devicesPassenger information systemsTicketing machinesTrackside applicationsDC power distribution systems.What is EN50155 and why does it matterThe EN50155 Railway Applications Electronic equipment used on rolling stock is a performance standard for electronic equipment found in railway applications. Its there to ensure that the components used can function in the rail environment. It specifies minimum standards to enable the reliable performance required such as operating temperature shock and vibration humidity and EMC.Things to consider when selecting a DCDC converter for a rail applicationThe major point to consider is the operating input voltage range of your supply for historical reasons there is a variety of standard voltages present in rail environments nominal ones being 24V 48V 72V 96V and 110V 110V is the most common on trains. EN50155 requirements mean that your dcdc converter needs to be able to cope with a wide fluctuation which for short periods this deviation can be anything between 0.6 to 1.4 times the nominal value.The majority of the products available from Delta and P-Duke are available in industry standard footprints and bricks being popular.
