Flex Power module Introduces power modules for railway vehicles

     Flex Power Modules has announced the PKJ7200 and PKJ7300 series of power modules for railway rolling stock equipment. These new modules are designed to meet the requirements of EN 50155 for railway applications, including a wide input voltage range, surge protection, power interruption and backup, a wide operating temperature range, and shock and vibration resistance.

     These modules achieve high efficiency of up to 92% at full load, which reduces power consumption. They are available in a compact half-brick package that provides high power density, which saves space.

     To cope with the many different voltages used on trains, they offer a wide input range of 60VDC to 160VDC. That is, they are able to handle harsh input voltage conditions, making it easier to reliably deal with power outages and transients that may occur in rolling stock. These modules provide input undervoltage protection (UVP) and output overcurrent protection (OCP), overvoltage protection (OVP), and overtemperature protection (OTP) to prevent damage to the modules themselves and the equipment they power.

     The output power of the PKJ7200 series is 200W, while the PKJ series is 300W. The output voltages of both series are 12V, 13.8V, 15V, 24V, 48V and 54V. Olle Hellgren, director of Product management and business Development for power modules at Flex, said: "Railway vehicles place demanding requirements on power components, such as wide voltage ranges, variable power supplies and harsh physical conditions. The new PSU PKJ7000 delivers the required reliability, performance and affordability."
