Rail – Rolling Stock

Flex Power Modules

DC/DC power solutions for rail – rolling stock

Flex Power Modules provides a series of power modules for railway systems designed to meet the most stringent electrical and environmental specifications.

Applications

• Monitoring and entertainment systems • Lighting and information systems • Broadcasting and communication systems • Door and signal systems • GPS and driving systems • Sensors

These products can work under dust, moisture, severe vibration and other harsh conditions. DC/DC converters for rolling stock are also subject to greater demands for operational safety, durability and thermal shock.

Flex Power Modules offers ultra-wide 12:1 input range solutions rated from 50 to 200 W which are now required by many of our world-wide railway customers. Features & Benefits • Compliant to EN50155, an internationally recognized standard for rolling stock equipment • Fully encapsulated converters • Ultra-wide input ranges from 12-160 V • Up to 4000 V isolation

For industrial applications, working from 12 or 24 V inputs, our forthcoming PNA series of Industrial Point of Loads housed in a small form factor and low-profile package offers customers increased design flexibility.

Time delay relays for railway applications

Electromechanical relay-output time relays are available with a number of different functions and assure isolation between input and output. SSR time relays have no moving parts to arc, a lifespan of up to 100x that of a relay-output timer. In addition, all solid state time delay relays are fully encapsulated to protect against shock, vibration and humidity, therefore ideal for Railway applications.

Applications

• Flashing light control • Furnace safety purge control • Motor soft-start delay control • Conveyor belt sequence delay • Power supply sequencing • Oven ignitor controls
