The MINMAX MKZI20-48S12 is a 20W isolated DC-DC converter from the MKZI20 series, specifically engineered for demanding railway applications. It operates with an ultra-wide input voltage range of 18-75VDC and provides a regulated 12VDC output at 1670mA, achieving a typical efficiency of 88% at maximum load.
This converter offers 3000VAC reinforced I/O isolation, crucial for high safety margins in rolling stock and trackside electronics. It is designed to withstand harsh environmental conditions, with an operating temperature range from -40°C to +88.5°C. Key features include under-voltage, overload/over-voltage, and short-circuit protection, along with remote on/off control and output voltage trim capabilities.
The MKZI20-48S12 meets stringent railway standards, including conducted EMI compliance to EN 55032/11 Class A, vibration and shock tests per EN 61373, and railway EMC standards like EN 50121-3-2. It is also certified to EN 50155 (IEC 60571) and fire protection standards EN 45545-2. Safety approvals include UL/cUL/IEC/EN 62368-1 and UL/cUL 60950-1, along with CE marking.
The unit is housed in an industrial standard 2" x 1" package and is designed for through-hole mounting. It requires no minimum load for operation, simplifying system design.
