Описание

Floor-standing 19" cabinets of the LINEA N series are designed to accommodate telecommunications and server equipment of various sizes, uninterruptible power supplies and batteries due to their reinforced design. The cabinets are made in a system of load-bearing structures of the 482.6 mm series in accordance with GOST 28601.2-90.

Cabinets of a collapsible design consist of a base, a double roof, vertical racks, profiles and doors. The cabinet design provides increased reliability and high load capacity. Access for equipment installation is possible from four sides through removable side walls, front and rear doors. The doors are easily removable with three-point locking and a rotary handle.

To ensure effective heat exchange and maintain the required temperature conditions, ITK fan panels of the PV series can be installed in the roof of the cabinet, up to 3 pieces per cabinet (depth 1000 mm). The roof, base and rear wall cabinets are perforated for installing ITK brush cable entries.

The cabinet is supplied with 19" G-shaped mounting profiles (4 pcs.), adjustable supports (legs) to compensate for uneven floors. It is possible to install swivel casters (not included in the package) simultaneously with the supports. The cabinet grounding kit allows you to connect all parts cabinets into a single grounding loop.The cabinets can be joined together using a connection kit.
