Neousys' PB-9250J-110V is a newly designed SuperCAP UPS that accepts 110V DC input for fast-growing railway applications. Consisting of eight 370F supercapacitors, the PB-9250J-110V provides 9250 watt-seconds of stored energy to sustain the back-end system for seconds to minutes during a power loss. Unlike traditional battery-based UPS systems, supercapacitors have a wide operating temperature range and a long service life of up to 10 years. Neousys' PB9250J-110V has an operating temperature range of -40 to 70°C and extremely high durability.
Thanks to Neousys' patented CAP energy management technology, the PB-9250J-110V offers advanced features such as real-time energy/power consumption monitoring, high/low voltage protection and automatic/manual shutdown control. It automatically manages boot-up and shutdown to help your system thrive on trains with unstable power supply. Additional digital output channels are included to indicate system status such as charge/discharge and power button control.
While computer systems are widely used in various railway applications, the electrical stability of railway vehicles remains a focus and is critical to system reliability. The PB-9250J-110V can protect the computer or other equipment against power interruption when a train passes through a crossing or a railway switch. In addition, with EN 50155 and EN 45545 certification, the PB-9250J-110V can be easily installed and used with existing computers/equipment or integrated with the on-board power distribution system.

To achieve a service life of > 10 years with 24/7 operation at 70°C, please charge the PB-9250J-SA to the 6525J energy level using the 4.8x SuperCAP Life Extension setting (please refer to the user manual for details). When the rated service life or cycle life is reached, the capacity of the supercapacitor may drop by up to 30% and the ESR may increase by up to 100% from the initial values.
** The backup time for uninterrupted operation may decrease when sustaining a back-end system with high power consumption. If your computer accepts only a constant voltage input, please consult Neousys Technology.
*** To ensure that the power backup operation of the PB-9250J works as intended, if your connected back-end system accepts only a constant voltage input, please contact Neousys Technology technical support.
