Power Supply Solutions for Modern Rail Architectures
How MTM Power Responds to New Requirements in the Rail Industry
Rail vehicles continue to evolve. New technologies, increasing digitalization, and growing demands for passenger comfort and energy efficiency are also changing expectations for onboard power supplies. Different onboard voltage systems, more powerful subsystems, and additional electrical loads all require reliable power.
Power supply solutions must be flexible, available over the long term, and scalable across a wide range of applications. At the same time, compliance with railway standards, compact designs, and high reliability remain essential requirements for use in rail applications.
MTM Power develops and manufactures DC/DC converters and AC/DC power supplies for demanding rail vehicle applications. By continuously expanding its product portfolio, the company helps vehicle manufacturers and system integrators implement modern vehicle architectures in a cost-effective and future-ready manner. Its current portfolio specifically addresses today's challenges in the rail industry.
Ultra-Wide Input Voltage Range for Different Onboard Power Systems
Whether it is in light rail vehicles, high-speed trains, or freight trains, different onboard power systems and subsystems operate with different voltage levels. For vehicle manufacturers, this often means multiple power supply concepts and increased integration effort.
With the new PURC60 and PCMDS60U-VT DC/DC converters, MTM Power covers an input voltage range from 14.4 to 154 VDC. This reduces the number of required product variants and simplifies integration across different vehicle platforms. Depending on installation requirements, the converters are available with an open housing design or with thermoselective vacuum encapsulation. A power boost of up to 150% provides additional power reserves for short-term peak loads.
With the announced PURC200 and PCMDS200U-VT product families, MTM Power will extend this concept to output power levels of up to 200 watts. Users benefit from scalable power supply solutions for different power classes and installation environments.
Railway-Approved 60 W Power Supplies with Flexible Mounting Options
In addition to flexible DC/DC converters, railway-compliant AC/DC power supplies are also essential components of modern rail architectures. With the PMAT60 and PCMAT60 series, MTM Power is expanding its portfolio with railway-approved 60 W AC/DC power supplies for the first time.
Both product series comply with the requirements of EN 50155, EN 61373, and EN 45545-2 and are available for both PCB mounting and chassis mounting.
Their wide input voltage range of 90 to 264 VAC enables operation on different supply networks. For subsystems requiring higher output power, the product family already includes additional 100 W and 150 W versions.
High Power Reserves for Energy-Intensive Applications
As the number of electrical loads in modern rail vehicles continues to increase, so does overall power demand. Communication, control, and safety systems require powerful power supply solutions with sufficient reserves to handle dynamic load changes.
The PWRC650 DC/DC converter delivers up to 650 watts of continuous output power and provides a Power Boost of up to 1,000 watts for short-term peak loads. The PWRC650 is already available, and a battery charger version is currently under development.
USB-C Charging Solutions for Modern Rail Vehicles
Passenger expectations continue to evolve as well. USB-C charging ports are increasingly becoming standard equipment in passenger areas and driver cabs, creating additional requirements for the onboard electrical infrastructure.
With the new PS-USBC15 and PS-USBC30 modules, MTM Power is expanding its product portfolio with USB-C charging solutions for rail applications for the first time. The company is also developing USB-C Power Delivery chargers with higher charging capacities for devices such as tablets and laptops, consistently expanding its portfolio in line with the ongoing digitalization of the rail industry.
Solutions for Today's and Tomorrow's Rail Projects
With its latest product innovations and portfolio expansions, MTM Power demonstrates how the challenges of modern rail architectures can be addressed through well-designed power supply solutions. Rather than focusing on individual products, the company continues to expand a comprehensive portfolio covering a wide range of power classes and applications, enabling system integrators to select the right solution for their specific requirements.
