Technical Characteristics:
Note: all the technical characteristics refer to a temperature of 20°C.
Note: the performances of lead-acid storage batteries are affected by their operating conditions: temperature, absorbed current, state of charge and age of the storage battery may cause significant variations in the data shown below.

Type: 24V battery kit, complete with battery charger, suitable for powering gate and door automation systems in the event of mains power failures.
Technology adopted: Storage of electrical power by means of maintenancefree hermetic lead-acid storage batteries
Charge/discharge voltage: 28V at maximum charge; 16V at maximum discharge (when it is totally exhausted, the battery is disconnected automatically) Current delivered: Rated 4A; 7.5A for 3 seconds, starting current
Storage capacity: 1.2Ah, corresponding to an autonomy of approximately 12 hours with the automation system in stand-by mode; or 5 minutes with a load of
4A corresponding to an average of at least 10 manoeuvres
Complete recharge time: Approximately 16 hours
Storage battery life: Estimated at 4 ÷ 6 years; or, over 1000 cycles for 30% discharge depth, over 500 cycles for 50% discharge, over 200 cycles for 100% discharge.
Ambient operating temperature: -20 ÷ 50°C (storage battery efficiency decreases at lower temperatures: at -10°C efficiency is 30%; storage battery lifetime
decreases at higher temperatures: at 40°C, lifetime expectation could be reduced to 2 years.
Use in acid, saline or potentially explosive atmosphere: No
Mounting and connections: Installation in the compartments provided in the control units or gearmotors. Connection via supplied cable.
Protection class: IP30 (to be used only inside control units or gearmotors or other protected environments)
