Ltd has released the IRQ series, a family of encapsulated DC-DC converters designed for industrial and railway applications from Murata Power Solutions.Īccording to Murata, the modules include the industry-standard quarter brick that offers packaging and pin configuration options that allow the system designer to choose the most effective solution for cooling and power delivery. The PKJ 7200W is provided in an industry-standard half-brick format, measuring 60.96 x 57.91 x 12.70 mm, and it will be available in July, 2021.The IRQ series power modules are suited for railway systems and industrial applications that require power conversation from either 96Vdc or 110Vdc bus voltages. Input to output isolation is 4000 V, and the available versions of the new converter can provide outputs at voltages of 12 V, 13.8 V, 15 V, 24 V, 48 V and 54 V. MTBF is 4 million hours.Įfficiency of the module is up to 90%. The module includes input under voltage protection, output over current protection, output over voltage protection, and over temperature protection. It is also compliant with the functional insulation and safety standard IEC/UL 62368, and the EN45545-2 railway standard for fire behavior of components. To ensure reliable operation, the new module will comply with the EN50155 specifications for surge protection, power interruption and backup with external circuitry, wide operational temperature, and shock and vibration. Olle Hellgren, Director Product Management and Business Development at Flex Power Modules, said: “The new module series expands our existing range for railway applications, taking their place alongside our PKM family of DC/DC converters, while providing twice the output power.” This makes installation, qualification and aftermarket support simpler – saving time and reducing costs. These voltages are defined by the EN50155 standard, which specifies the various nominal voltages in use, as well as variations due to voltage spikes and dips.ĭue to its wide input voltage range, which covers the standard’s defined values, the PKJ7200W can be used in railway applications anywhere in the world, where previously at least two product variants would be required. Provided in a half-brick format, the PKJ7200W delivers up to 200 W output power, with an ultra-wide input voltage range of 14 V to 160 V.Įquipment for use in railway rolling stock must meet a wide range of standard input voltages, which varies between countries.
