Professional 150W DC-DC Converter for High Efficiency

MRZI150 series 150W DC-DC converter is a kind of high-performance railway DC DC converter. Its packaging adopts 1/4 brick type package, and its input voltage range is designed at 36-160 VDC, which is general for railway applications. The output voltage of MRZI150 series 150W DC-DC converter is ranged 5V, 12V, 15V, 24V, and 54V. (54V is suitable for PoE applications)

Because equipped with advanced circuit topology, MRZI150 series 150W DC-DC converter can provide outstanding efficiency of up to 90%. It even can meet 100% current and power requirements of the back-end load system to quickly supply the rated output voltage and meet the optimized system load driving capability requirements no matter the drastic changes that happen to the input voltage, output current, and ambient temperature, meeting the high standard needs in railway applications.

Moreover, MRZI150 series 150W DC-DC converter is equipped with a heat dissipation management structure design such as a high thermal conductivity metal casing, high thermal conductivity adhesive, and optimized heat dissipation PCB layout, which can make sure its long-term thermal performance and reliability, allowing the chassis temperature to reach 105°C. In addition, it is also designed with 2000VAC isolation to withstand voltage and a reinforced insulation system, which can effectively avoid damage to the back-end system and even personal injury due to sudden lightning strikes. If you want to improve the thermal performance of the MRZI150, MINMAX DC DC converter manufacturer also provides 3 radiators of different heights and sizes to meet the needs and occasions of different operating temperature ranges.

To meet the high standard of safe conditions, MRZI150 series 150W DC-DC converter has passed the following certifications:

● Railway Code Certification EN 50155 (IEC 60571)
● Fire Test Code Certification EN 45545-2
● Safety Code Certification IEC/EN/UL 62368-1

MRZI150 can also support operations at an altitude of 5,000 meters and has positive/negative logic remote control switches, output voltage trimming, and output voltage sensing functions to provide customers with more flexible design requirements. Protective functions for abnormality include input under-voltage protection, output over-current protection, output short-circuit protection, output over-voltage protection, and over-temperature protection to ensure that when an abnormal operation happens, the power module and the back-end system can be protected immediately.
