SITOP BAT1600 DC 24 V 12 Ah Pb battery module with maintenance-free sealed lead batteries for SITOP UPS1600 The maintenance-free battery modules with lead batteries SITOP BAT1600 are an important component of DC UPS systems. In combination with a 24 V power supply and a UPS1600 module, they enable buffering of power outages lasting up to several hours. The intelligent battery management of the UPS1600 charges the BAT1600 with the optimal temperature-controlled charging characteristic and monitors the status (operating data and diagnostic information) of the connected battery modules via Energy Storage Link. For longer buffer times, up to six battery modules can be connected in parallel. They are attached using wall mounting.
