The DIN-RAILway power supplies from PULS represent a new range of railway power supplies whose concept has already been proven in tens of thousands of industry applications worldwide. What distinguishes the new PULS DIN-RAILway power supplies is the extremely simple DIN-rail fixation.

Railway / Train

The performance requirements for railway applications are challenging on several fronts: Failures cannot be tolerated, even under extreme mechanical stress over an extended temperature range. Historically, the input voltages in railways differ from those experienced in industrial applications.

PULS power supplies are certified to fulfil railway standards

A complete range of 1- to 3- phase units and DC/DC converters are currently available, all of which can be mounted on DIN rails and are certified to comply with the common railway standards: 

  • EN 50155 Railways Applications  - Electronic equipment used on rolling stock

  • EN 61373 Rolling Stock Equipment – Shock and vibration tests

  • EN 50121-3-2 Electromagnetic Compatibility – Rolling stock – Apparatus

  • EN 45545-2 Fire Protection on Railway Vehicles

The units are: convection cooled, operational down to -40°C; equipped with vibration-compensating spring clamp terminals, conformal coated, extremely lightweight in a compact housing and exhibit the highest level of efficiency. PULS DIN-Railway customers also receive the benefits of the logistical resources of a large-scale manufacturer.

PULS DIN-rail power supplies can be used both within the train and on the track.
