Power modules are for railway rolling stock
Two modules announced by Flex Power Modules are designed for railway rolling stock equipment. The PKJ7200 and PKJ7300 series of power modules are designed for the demands of the EN 50155 standard for railway applications, including a wide input voltage range, surge protection, power interruption and back-up, wide operational temperature range and resistance to shock and vibration.
The modules achieve high efficiency of up to 92 per cent at full load, which reduces power dissipation. They are supplied in a compact half-brick package for use in space constrained areas.
They have a wide input range of 60 to 160V DC, sufficient to handle the multiple different voltages used on trains. They are therefore capable of handling harsh input voltage conditions, making it easier to cope reliably with the brownouts and transients that can occur in railway rolling stock. To protect both the modules and the devices they power, the modules provide input under-voltage protection (UVP) and output over-current protection (OCP), over-voltage protection (OVP) and over-temperature protection (OTP).
The PKJ7200 series offers 200W of output power, while the PKJ7300 series delivers 300W. Both series provide output voltages of 12, 13.8, 15, 24, 48 and 54V.
Flex Power Modules has released the first two devices, the PKJ7216 and PKJ7316, which are available now in OEM quantities.
The company’s portfolio of power modules for railway applications will be highlighted at the Modern Railways 2019 show at the China National Convention Center in Beijing (20 to 22 November) on stand 2040.
Flex Power Modules designs and manufactures scalable power supplies that improve the operational efficiencies of advanced data centre, IT information and communications networks.
