Battery deep discharge protection

The ZB-1 module is a safety device designed to protect battery from deep discharge that would significantly reduce its life. If a dangerously low voltage level is reached, the load is disconnected. The module is designed to work in conjunction with devices included in the alarm, access control or video systems whose power supply system does not have any protective function (all SATEL control panels are fitted with such protection as standard). ZB-1 increases the efficiency of the power supply systems compatible with gel or AGM batteries having a rated voltage of 12 V. The maximum load current is 7 A.

  • battery disconnecting to prevent deep discharge
  • compatible with all alarm panels not equipped with such feature
