Ring Engineering Rail Pro PBM-2 Power Backup Module

Ring Engineering PBM-2 Power Backup Module

A PBM can be added to a HO model train locomotive so that if the model train wheels loose connection from the track because of dirty track or other problems, the Power Backup Module will supply power to the Locomotive Module for up to many seconds to keep operating properly without sounds, lights, or even motor stopping!

What is special about the RaiPro PBM is that the PBM is an active power backup not a passive one like many other power backups. Many others are basically just super capacitors that the voltage drops exponentially as soon as the power is removed. With other backups, lights continually dim and module performance is effected. Our PBM has onboard microcontroller and other electronics that will output a fixed voltage similar to a good power supply output so lights stay constant while PBM is active and locomotives perform better.
