Quarter Brick DC-DC Converter

Overview

MRZI100 series from MINMAX DC DC converter manufacturer is ideal for railway applications. Its input voltage range is designed at 36-160 VDC, which is suitable for applications that require low voltage startup. The packing style of MRZI100 100W DC-DC converter is an international 1/4 brick type package.

To avoid the damage of lightning strikes, MRZI100 series 100W DC-DC converter has a 2000VAC isolation withstand voltage and a reinforced insulation system. In addition, MRZI100 series passed up to 500 times of cold and heat cycle tests to ensure thermal performance and reliability for long-time use, making the temperature reach 105°C but still operating smoothly based on heat dissipation management structure design.

MRZI100 100W DC-DC converter is able to meet 100% current and power requirements of the back-end load system, offering the rated output voltage. Because of its outstanding circuit topology, the efficiency of MRZI100 is up to 91.5%. Even at the moment of the startup, it can still keep high stability of overall efficiency, power loss, and heat generation. Besides, it also passed the Railway Code Certification EN 50155 (IEC 60571), Fire Test Code Certification EN 45545-2, and Safety Code Certification IEC/EN/UL 62368-1.

To provide more flexible design requirements, MRZI100 100W DC-DC converter owns output voltage sensing functions as well as positive/negative logic remote control switches. Also, it is equipped with abnormality protective functions like output short-circuit protection, input under-voltage protection, over-temperature protection, etc. to make sure that the power module and the back-end system can get immediate protection when an abnormal operation.
