Made by TracoPower, both models feature a professional battery management system to charge and monitor an external battery. In the event of a power failure the battery is switched without any interruption to the DC output. Once mains power is restored, the battery is switched off. Back up time is limited only by the battery capacity and load current. Charger voltage/current can be adjusted to suit the battery type.
The units feature power fail and low battery alarm signals and, during normal operation, battery status is checked periodically while the external battery is fully protected under any operating conditions. Powersolve can supply external battery packs as required.
