Murata’s rail, transportation, and industrial DC-DC converters are designed to provide isolated DC power for applications requiring high reliability in demanding conditions.
Using the latest technology development, Murata’s DC-DC converters can cover a wide range of battery input voltages from 9V to 160V DC in a single module (with input voltage ratios up to 10:1). Specific nominal battery input voltage range converters are also available. Products are suitable for both onboard and trackside rails applications, as well as industrial/manufacturing and farming equipment, and e-mobility applications.
Murata’s IR series is designed for transportation applications such as the driver’s and traveler’s cabins, facilities, propulsion, and trackside. The IR series features:
- • ½, ¼, ⅛, 1⁄16 brick formats
- • Input voltage ranges from 9-160V
- • Stable no-lead operation
- • -40°C to 85°C (ambient) and 110°C (case) operating temperature
- • Baseplate and flange package options
- • Baseplate and flange package options
- • High efficiency up to 91.5%
- • 3.3V, 5V, 12V, and 24V output
- • Tight line and load regulation
- • 3000V RMS input/output isolation
- • Dipped varnish coating
Construction
The IR series offers the following benefits in its construction:
- • Baseplate machined from a single block of aluminum
- • High-quality and high-conductivity thermal interface materials
- • Plastic components with temperature ratings >300°C
- • Conformal coating with Cytec CE-1171 and qualified to meet IPC-CC-830B
Testing and compliance
For rail applications, both onboard and trackside environments have been carefully considered, while meeting the constraints of EN50155:2017.
Wide DC input ranges cater to the battery-powered applications for both 12V and 24V systems, offering the highest power density packages available on the market. Murata’s industrial DC-DC products use the latest and most efficient architectures and components for power conversion along with proprietary packaging materials and processes.
To ensure robustness, Murata enforces strict engineering design for reliability processes to maximize the life of the product.
Engineering policies and procedures include strict component derating guidelines to ensure low electrical stress, as extensive EVT/DVT testing and evaluation. Each module design is subject to extensive design review stages and rigorous HALT/HASS testing for electrical and mechanical stress testing.
