Eaton Unveils New Martek Power PME Series DC/DC Converters for Rail Applications
SOUTHFIELD, Mich. … Intelligent power management company Eaton today announced the launch of its new Martek Power PME family of DC/DC converters, specifically designed for rail applications. This new series offers highly efficient, compact chassis-mount converters that are fully compliant with the latest European rail standards, ensuring optimal performance and safety for electronic equipment used on-board rail vehicles. The PME series meets rigorous standards including EN 50155, EN 50121-3-2, and EN 45545-2.
The PME Series is available in three distinct power levels: 75W (PMEL), 150W (PMEM), and 300W (PMEH). The PMEL and PMEM models feature an ultra-wide 10:1 input voltage range of 14.4 – 137.5 volts (V) direct current (Vdc), making them versatile enough to cover all nominal battery voltages within a single model. Additionally, these models offer output voltage options of 12V, 15V, or 24V. The PMEH model, available with dual input ranges of 24/36V and 72/110V, provides output options of 15V or 24V. All models in the PME Series are fully isolated, ensuring high efficiency and reliable operation in a wide ambient temperature range of -40℃ to 70℃ without de-rating.
In addition to their robust design, all models in the PME Series include isolated output voltage monitoring as a standard feature. The 300W PMEH model also offers output current sharing, coupled with a low-loss output series device, allowing two or more converters to be connected in parallel. This enables increased system power or redundant operation, providing flexibility for rail system designers.
The versatile PME Series DC/DC converters are capable of powering a broad range of critical systems on trains, including:
HVAC (Heating, Ventilation, and Air Conditioning)
Cab Radio
Onboard Computers
LED Lighting
Passenger Information Systems
Video Surveillance and Security
Door Control Systems
Traction Control
Brake Systems
The Martek Power PME Series is designed to meet the stringent requirements of the rail industry, providing reliable power conversion solutions that are both efficient and compact. With compliance to the latest European rail standards, the PME Series is a significant step forward in enhancing the safety, reliability, and performance of on-board rail systems.”Mike Carter, Manager, Cambridge, U.K., Eaton’s Mobility Group.
