Flex Power Modules introduces power modules for railway rolling stock

Flex Power Modules has announced the PKJ7200 and PKJ7300 series of power modules for railway rolling stock equipment.

The 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 backup, wide operational temperature range, and resistance to shock and vibration.

They achieve high efficiency of up to 92% at full load, which reduces power dissipation, and are provided in a compact half-brick package, delivering high power density and saving space.

To handle the multiple different voltages used on trains, they have a wide input range of 60VDC to 160VDC. This means they are 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 against damage for 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 PKJ series delivers 300W. Both series provide output voltages of 12V, 13.8V, 15V, 24V, 48V and 54V.

The first two devices in the new series, the PKJ7216 and PKJ7316, is available in OEM quantities.
