MINMAX Technology Company designs and manufactures DC/DC converters and AC/DC power supplies for railways according to industry standards.

The railway-certified DC/DC converter range supports powers ranging from 3W to 75W, designed in accordance with stringent requirements and intensive environmental testing. MINMAX aims to make it the insulation barrier of choice for railway DC power infrastructure.

DC/DC converters for rail applications

MINMAX converters are available for DC battery bus voltages of 24VDC, 36VDC, 48VDC, 72VDC, 96VDC, and 110VDC. Converters are also provided for output voltages of 5VDC, 12VDC, 15VDC, 24VDC, ±12VDC, and ±15VDC.

MINMAX power converters conform to the railway DC input-voltage range and brief variation requirements in accordance with EN50155 certification.

Testing for voltage isolation, vibration, and shock and bump is approved to EN61373 requirements. Cooling, dry, and damp heat levels are approved to IEC-EN 60068-2-1, 60068-2-2, and 60068-2-30 test requirements, as well as the EMC railway standards in EN50121-3-2.

Advanced circuit topology provides efficiency of up to 93%, which allows for a baseplate temperature of around 105°C and a minimum of 3,000VAC input to output isolation with reinforced insulation.

Converters are protected against overload, overvoltage and short-circuiting. They are approved to the EN45545-2 standards for fire protection to ensure system safety. Other features include remote power control and voltage output trim and sense.

Rail voltage converting solutions

The MINMAX product range includes railway-certified power solutions with the 3W to 75W DC/DC converters in the DIP / 2in × 1in / Quarter Brick packages and ultra-high isolation power solutions with the 1W to 20W DC/DC converters in the SIP / DIP / 2in × 1in packages among others for medical safety power solutions.

General industrial power solutions also include:

  • 1W to 60W DC/DC Converters in the SIP / SMD / DIP / 1in ×1in / 2in × 1in / Chassis / DIN / Rail Mounting
  • 2W to 60W AC/DC power supplies in the PCB / Chassis / DIN-Rail Mounting
  • 5A to 1A Switching Regulator

Safe railway power supplies

DC/DC converters have a vacuum-sealed packaging and use UL94V-0 grade sealants. All MINMAX railway-certified power modules are evaluated based on the final test results of the fire safety index parameter to ensure safe railway operation.

The 3,000VAC isolation voltage with reinforced insulation and vacuum-seal creates a solid electrical barrier to protect sensitive circuit load from excess energy hazards. This ensures safety in the long-term operation of railway equipment.

Energy-saving DC/DC converters

Advanced environmentally friendly technology used by MINMAX helps save energy, minimise temperature rises and prolong battery life. The technology provides high efficiency for whole output loads, input lines and ambient temperature ranges.

The high-stability feedback loop design provides consistency even in light or no load conditions.

Quick start-up power converters

MINMAX railway-certified power converters start-up in 20ms, improved from 250ms to avoid any system timing failure caused by long start-up times. Faster start-up time without overshoot ensures the safety of your system.

Protection against converter malfunction

MINMAX converters offer long-term system protection against hazards, including:

  • Under-voltage
  • Short-circuiting
  • Overload
  • Over-voltage
  • Output voltage trim
