Innovative, high performance LEDs receive Network Rail certification
Marl International announced today that its 407 series of LED indicators has received a certificate of acceptance from Network Rail for use on railway infrastructure applications. This certification paves the way to bringing energy efficient LED technology to every rail signalling application including control units and signal box diagrams, for new installations and retrofits alike.
CommHigh visibility is an important factor in signalling applications and the newly certified 407 series addresses this with a flat diffused assembly providing excellent viewability over a wide angle, even in sunlight. The 407 series is available in red, yellow, green and white, with a black precision moulded housing that greatly enhances mechanical stability and supports the standard intensity LED element and internal circuitry for both 12 and 24V DC operation.
A flush mounted design allows for quick and efficient replacement in front panels, and the mandatory 907-000-00 panel socket has also been certified by Network Rail.
Typical lifetime is 90,000 hours and operating temperatures range from -40 to +80 or -40 to +85 degrees dependant on selection of part.
