The TRC-190-DC-48 from Moxa is an industrial 19-inch rackmount housing, serving as a base for modular network and communication solutions in industrial environments. It offers up to 19 slots for modules from the CSM-200 series (Ethernet-to-fiber) or the TCF-142-RM series (Serial-to-fiber), making it particularly suitable for dense network infrastructures in data centers, enclosures, and communication centers. The housing features a fanless design, enabling nearly maintenance-free operation and reducing long-term operating costs.

Applications
The TRC-190-DC-48 is designed for use in industrial networks where a high density of media converters or interface modules is required. It is used in environments where stable, redundant power supply and compact mounting in standard 19-inch racks are necessary. Its use in enclosures or communication centers benefits from its compact form factor and high module capacity.

Functions and Equipment in Detail
The housing supports redundant power supply with interchangeable power supplies. The TRC-190-DC-48 variant is designed for an input voltage of 48 VDC and can be operated in parallel with a second power supply to ensure higher fault tolerance. The power supply is equipped with overcurrent protection, enhancing operational safety. Power consumption is 3.2 A at a voltage of 36 to 53 VDC.

Technology Explained Simply
The fanless design reduces the number of moving parts, thereby minimizing wear and failure risks. Cooling is passive through the housing construction, which is particularly advantageous in environments with limited space or high dust levels. The protection rating IP30 protects against solid foreign objects with a diameter of at least 2.5 mm and provides some protection against contact with tools. The housing is designed for an operating temperature of 0 to 60 °C, making it suitable for use in controlled indoor environments.

Compatibility and Accessories
The TRC-190-DC-48 is specifically designed for modules from the CSM-200 series (Ethernet-to-fiber) and the TCF-142-RM series (Serial-to-fiber). Combining it with the TRC-190-AC power supply enables flexible power concepts, with both variants (AC and DC) being operable in parallel within a system. Certifications include EMI/EMS according to EN 55032/35, CISPR 32, and FCC Part 15B, as well as safety standards according to IEC/UL 62368-1. The MTBF is 1,055,112 hours, indicating high reliability.

Mounting and Installation
The housing is designed for mounting in standard 19-inch racks. Dimensions are 440 x 260 x 88 mm, with a mounting height of 19 units. Installation is carried out using pre-drilled mounting screws, which are included in the delivery scope.

Operational Advantages
The combination of fanless design, redundant power supply, and high module capacity ensures reliable and low-maintenance operation. Passive cooling reduces noise generation and maintenance effort. The high MTBF and compliance with international standards for EMI, safety, and vibration ensure stable operation in demanding industrial environments.
