Schroff produces shock-resistant subway cabinet
Schroff
Varistar cabinet
Electronics enclosure manufacturer Schroff has introduced a range of rugged 19in cabinets specifically developed to handle the rigorous demands of underground railway applications.
Utilising an alternative cable-channel design, the Varistar cabinet achieves EMC performance while reducing installation time by allowing existing cable assemblies to be routed into the cabinet without the need for re-termination.
Offering a static load-carrying capacity of up to 800kg, the cabinet features a closed rolled-steel frame construction for high stability and resistance to shock and vibration.
Tests carried out in accordance with IEC 61587-1 indicate a shock resistance of up to 5g and an earthquake resistance up to Bellcore Zone four.
The range includes standard configured cabinets in two sizes of 38U and 43U.
The smaller version has overall dimensions of 1,800 x 600 x 600mm and features a single 100 x 100mm cable channel.
Equipped with a 48VDC fan tray, it can be specified with or without battery shelves.
The larger 43U model measures 2,000 x 600 x 800mm and has a double cable channel, which makes it particularly suitable for use where numerous cables need to be fed into the cabinet.
This model is equipped with a 230VAC fan tray.
Front and rear-doors are vented and fitted with dust filters, and the cabinets are finished in London Underground approved low smoke, halogen free (LSHF) light-grey paint.
All plastic parts carry a UL 94 V-0 flammability rating.
