Murata the IRS Series encapsulated, 1/16nth brick dc/dc converters for industrial, railway, and industrial mobility applications. Features include a 4:1 input range, support for bus voltages of 24V, 28V, 37.5V, 48V, 54V, shock-and-vibration tolerance that meets or exceeds EN 61373:1999 Category 1, Class B, Body Mounted requirements, and an efficiency of 91%. The components are available with an option for a standard or a flanged baseplate for various conduction cooling configurations including cold wall mounting. Other features include:
- Baseplate cooling
- On/off logic control
- Output short circuit & overvoltage protection, along with, input under voltage lock out (UVLO) over temperature protection circuits
- Basic insulation with 2,250-Vdc input-to-output isolation and a fully regulated DC output
- Includes modules with outputs of 3.3, 5 and 12 Vdc with up to 50W of output power
- The universal Vin range of 18 – 75 Vdc meets the requirements of EN50155 for nominal input voltages of 37.5 Vdc and 48 Vdc including brown out and transient conditions
Of course, more enlightenment awaits via the IRS Series datasheet.
