Description

With connections for a lead-gel rechargeable battery 1130 00 for buffering KNX voltage in case of a power failure. Up to two lead-gel accumulators can be connected and charged via the uninterruptible power supply. The charging voltage is controlled depending on the temperature using a temperature sensor.

The uninterruptible power supply has a zero-voltage 2-way switch for reporting a fault (e.g. mains failure, battery failure, overload or short circuit). Connection is made via KNX bus connection or branch terminals (no data rail required).

  • Lead-gel rechargeable battery 12 Ah: 1130 00 
  • Basic cable set: 1128 00
  • Expansion cable set: 1129 00
