MINMAX Introduces MIZI03 Series Within Encapsulated DIP-24 Package

The new range of high-performance 3W isolated DC-DC converters has been specially designed to meet stringent requirements in railway systems. 

MINMAX Technology has announced the launch of MIZI03 Series, a new range of high- performance 3W isolated DC-DC converters, specifically designed for critical railway applications.

The new MIZI03 power converter series, encapsulated within DIP-24 package, is now available for DC battery bus voltages of 24VDC, 36VDC, 48VDC, 72VDC, 96VDC, and 110VDC, with output voltages of 5VDC, 12VDC, 15VDC, ±12VDC, and ±15VDC.

The high-performance 3W isolated DC-DC power converters comply with Railway DC input-voltage range and brief variation requirements in accordance with EN50155 certification, vibration and thermal shock test EN 61371, cooling, dry, and damp heat test IEC/EN 60068-2-1, 2, 30, Railway Certification EN50155 (IEC 60571), and Railway EMC standard EN 50121-3-2. The DC-DC power converter series are designed-in conducted EMI filters EN55032/11 Class A & FCC Level A, conforming to voltage isolation requirements EN 61373.

The industry-leading power converter MIZI03 series ensures high-grade security of the system by incorporating top-class safety features such as voltage output trim and remote power control, along with overload, overvoltage, short-circuiting, and fire protection approved to the EN45545-2 standards.

The entire MIZI03 series 3W isolated DC-DC power converter range has been evaluated based on safety index parameters to ensure superb reliability and safe railway operation. The railway-certified DC/DC power modules are vacuum-sealed, using UL94V-0 grade sealants. The vacuum-seal of the DC-DC power converters and the 3,000VAC voltage isolation with reinforced insulation create a robust electrical barrier to secure sensitive circuit load from excess energy mishaps.

This ensures the safety of the equipment in rugged, long-term railway operations. The state-of-the-art protection features integrated by the leading DC-DC power converter series include under-voltage, short-circuiting, overload, over-voltage, and output voltage trim.

Quick Start-Up and Energy Saving Features of MINMAX MIZI03 Series Railway-Certified Power Modules

The 20ms quick start-up feature in the railway-certified MIZI03 DC-DC power converter series eliminates system timing failure caused due to long start-up times.

The speedy start-up time without overshoot, and protection against converter malfunction, enable ultimate safety of the system. In addition, the advanced, environment-friendly technology introduced in the MIZI03 series minimizes temperature rises, ensures superior energy savings, and prolongs the railway battery life. The technology enables high-efficiency for input lines, output loads, and ambient temperature ranges.

Furthermore, the high-stability feedback loop design of the MIZI03 DC-DC power modules provides outstanding consistency even in light or no-load conditions.
