Available now from Luso Electronic Products, the P-Duke have released the RCD30W series, a 30W high-performance DC-DC converter created for ruggedised railway and industrial applications. It extends its railway converter range of 10W to 20W in its compact 1”x1” package. The series offers 4:1 input voltage ranges of 9-36V, 18-75V, and 36-160V, perfectly fitting the supply voltages of rolling stock equipment.


The series consists of single and dual output models including 3.3, 5, 5.1, 12, 15, 24, ±12, ±15, and ±24V output voltage and have circuits for over/under-voltage, over-current, short-circuit and over-temperature protection.


The converters offer high efficiency of up to 92% that generate less power loss and allow operating temperatures with heat-sink at a full load of up to 73C ambient temperature (natural convection cooled), which satisfies the criteria of operating temperature class OT4, in accordance with EN 50155. The suffix 'M3' refers to an option that enables the converter to function at extremely low start-up temperatures -55C, made specifically for demanding, ruggedised railway and industrial applications in extreme temperature environments.


The 1”x1” compact package simplifies the design, saving up to 50% space on the PCB. According to IEC/EN/UL 62368-1, EN 50155 and EN 45545-2 Standards, this series is certified. Furthermore, shock and vibration levels are compliant with EN 61373 and MIL-STD-810F. With an operating altitude of up to 5000m, a wide operating ambient temperature of -40C to +105C and a 4:1 input voltage range makes these converters ideal for any ruggedised, high-reliability application, such as for rolling stocks and transportation or in harsh industrial environments.
