For system integrators, panel builders, and procurement engineers, housing sensitive electronic equipment in industrial environments requires more than a standard enclosure.
In addition to mechanical protection, factors such as thermal management and electromagnetic compatibility (EMC) play a critical role. EMC 19-inch cabinets are designed to support these requirements and can help protect automation, communication, and power distribution systems from environmental and electromagnetic influences.
The TPS 15U 19-inch Industrial Cabinet is a free-standing rackmount enclosure developed for industrial applications. With its modular construction, integrated grounding concept, and pre-configured components, it is suitable for use in control systems, factory environments, and technical infrastructure installations.
What Is an EMC 19-Inch Cabinet?
An EMC (Electromagnetic Compatibility) 19-inch cabinet is an enclosure designed to reduce electromagnetic interference (EMI) and radio frequency interference (RFI).
In industrial environments where equipment such as variable frequency drives (VFDs), power electronics, and communication systems operate in close proximity, unmanaged interference can affect signal integrity and system performance. EMC cabinets are used to mitigate these effects.
Typical design characteristics include:
- Conductive gasket systems to maintain electrical continuity
- Bonding of doors, panels, and frame
- Shielding concept comparable to a Faraday cage
- Standardized 19-inch mounting format in accordance with IEC 60297
This allows integration of standardized components while supporting EMC requirements.
TPS 15U Industrial Cabinet: Overview
The TPS 15U cabinet is manufactured from sheet steel with a powder-coated surface (RAL 7035) and is designed for industrial use.
Key characteristics:
- Free-standing design for flexible installation
- Modular construction for different configurations
- Suitable for high component weight and static loads
- Optional castors (GD-80 with Fuma bearings) for mobility
The cabinet can be used as a PLC rack enclosure, industrial data cabinet, or for general control system integration.
3U vs. 4U Chassis Versions
The cabinet is available in different internal configurations to support various application requirements.
3U Version
- Includes multiple mounting brackets (3 × 3U)
- Equipped with components such as limit switches, relays, and circuit breakers
- Net weight: approx. 110 kg
4U Version
- Configuration with 2 × 4U mounting brackets
- Adapted component layout for different integration needs
- Net weight: approx. 125 kg
Both versions include a 4.0 mm grounding copper plate as part of the EMC concept.
For larger installations, additional cabinet sizes (e.g. 24U, 42U) are available.
Mechanical Design and IP54 Protection
The cabinet design focuses on accessibility, durability, and safe operation.
Features include:
- Front and rear doors with reinforced construction
- Opening angle up to 150°
- Locking system with rod fasteners
- Integrated door stoppers for maintenance safety
The enclosure is designed to meet IP54 protection requirements, helping to reduce dust ingress and protect against splashing water.
Additional mechanical features:
- Removable top and bottom panels
- Cable management tray
- Lifting points for installation
EMC Shielding and Grounding Concept
Effective EMC performance depends on a consistent grounding strategy.
The cabinet includes a grounding copper bar that connects all conductive parts, including:
- Frame
- Doors
- Side panels
This bonding approach helps maintain a uniform ground potential. In combination with conductive gaskets, it can reduce high-frequency interference within the enclosure.
Thermal Management and Airflow
Thermal management is an important consideration in cabinet design.
The 19-inch mounting structure allows flexible placement of components to support airflow. Additional options include:
- Installation of fan trays
- Passive ventilation openings
- Structured cable routing to avoid airflow obstruction
These measures can support heat dissipation in applications with power supplies, control systems, or server components.
Custom Rack Enclosure Configurations
Industrial applications often require project-specific adaptations.
Custom configurations may include:
- Integration of emergency stop buttons
- Pre-installed power supplies
- Specific terminal blocks or copper busbars
- Application-specific layout adjustments
Such configurations are typically defined based on project requirements and technical specifications.
