ATS125x 4-Door DGP Installation Manual
• The required battery current is dependant on the approval grade. See “Auxiliary current and
battery capacity” below for determining which current should be reserved for charging the
battery. Note that auxiliary power, lock power, and local databus power is limited by the battery
current.
• For the 12 V model 3900 mA can be distributed. Higher current value drives the power supply into
current limit.
• For the 24 V model 1600 mA can be distributed over 27.6 V contacts (Locks and Battery) and
1000 mA can be distributed over the 13.8 V contacts (auxiliary power incl. switched and the local
communications).
