Modular outdoor cabinet provides protection for railway applications

01 April 2019

Foremost Electronics now offers the redesigned nVent SCHROFF Outdoor Modular Cabinet which features many functional improvements.

In addition to meeting the relevant international standards and norms, the improved nVent SCHROFF Outdoor Modular Cabinet also complies with relevant railway certification. The cabinet provides reliable protection against environmental conditions including heat, cold, wind, moisture, dust and risks including shocks and vibrations as well as intrusion and vandalism for electronics installed in outdoor trackside railway applications (e.g. at stations, signal boxes and level crossings). This increases the security and reliability of the applications, extends the product life cycle and reduces overall operating costs.

To ensure an optimal operating temperature range inside the cabinet, different options can be incorporated within the nVent SCHROFF Outdoor Modular Cabinet. Its double-walled design alone can dissipate a thermal output of up to 24watts. The standard outdoor modular cabinet for railway applications is equipped with active cooling by way of a fan kit. The two integrated 24VDC fans in the top of the cabinet draw cold air through the doors and blow heated air out through the outer roof and provide a heat transfer coefficient of 160 W/K and an air flow capacity of 540m³/h. It is also possible to equip the cabinet with air-conditioning units.

The aluminium profile frame and double-walled design of the cabinet offers rigid structural stability with a static load of 400kg. The particularly robust design is further realised by corner blocks integrated in the cabinet frame and by aluminium profile hinges for the doors. The cabinet has passed all relevant shock and vibration, wind as well as seismic tests with very good values.

An earthing kit with central earthing point provides the necessary equipotential bonding. Comprehensive EMC protection is ensured by the inner panels, which fully line the aluminium frame. This protection can be extended as an option.

The high level of robustness and stability of the nVent SCHROFF modular outdoor cabinet protects against vandalism and unauthorised access, while the newly designed panels, hinges and locks further increase this protection. The outer panels comprise 1.5mm thick, zinc-magnesium-coated steel, and are additionally powder coated on the outside. The inner panels comprise 1mm thick aluminium sheet metal. All wall screws are vandalism-proof and can only be accessed from inside the cabinet. The top cover, side panels and base plinth covers can only be removed when the doors are unlocked.

Alan Vincent, Sales Director of Foremost, comments, “The updated nVent SCHROFF Outdoor Modular Cabinet offers designers and systems integrators market leading environmental and safety protection for electronic equipment required by modern railways. The range of customisation, accessories and factory installed sub-systems allows users to specify complex systems reducing vendors and lead-times and increasing reliability.” 

The nVent SCHROFF outdoor cabinet is very versatile and can be adapted to suit individual requirements. This is facilitated by the scalability of the cabinet’s design as well as by the wide selection of 19-inch accessories. The cabinet is adjustable in width from 700 to 2,000mm, in height from 1,000 to 2,100mm and in depth from 500 to 1,200mm in 50mm increments. The design allows access to the inside of the cabinet from all sides so that installation, maintenance and repair work on the installed components can be easily carried out. 

nVent also offers the option of integrating various components as a service. Batteries, rectifiers, converters and UPS systems can likewise be integrated as are the requisite cabling, components for environmental monitoring (EMX), control panels and redundant cooling. In addition, nVent assists its customers with testing and simulations in its own laboratories to ensure that the requirements placed on the cabinet are fulfilled.
