WARNINGS:
– The PS524 unit is produced by Nice S.p.a. (prov. of Treviso – Italy)
- All technical specifications stated herein refer to an ambient temperature of 20°C (± 5°C).
- Nice S.p.a. reserves the right to apply modifications to products at any time when deemed necessary, maintaining the same intended use and functionality.
– The performance of lead acid batteries depends on their conditions of use: the temperature, current draw, charge level and age of the battery can all signifi-
cantly affect the cited data.

Electronics kit for charging lead acid batteries for powering automations for automatic gates and doors in the event of a
mains power failure
Recharging of maintenance-free sealed lead acid batteries and supply of continuous power to the automation in case of
mains power failure
two rechargeable sealed lead acid batteries (VRLA 12V 7 A/h) such as Ultracell UL 7.2 - 12 - 12v 7.2AH ( Nice art. B12-B)
28V at maximum charge; 16V at maximum discharge (the battery is disconnected automatically when totally drained)
15A nominal; 30 A for 0.5 seconds at startup
7.2 Ah, corresponding to an autonomy of approx. 30 hours with automation in stand-by or 12 minutes with 15 A load
approx. 14 hours
estimated 4 - 6 years; or over 1000 cycles for discharge level of 30%, over 500 cycles for discharge at 50%, over 200 cycles
for discharge of 100%.
- 20 to + 55°C (battery efficiency is reduced in proportion to a decrease in temperature, at -10°C efficiency is 30%; the bat-
tery lifetime decreases on an increase in temperature; at 40°C lifetime may be reduced to 2 years)
NO
Insertion in specific compartments in control units or gearmotors. Connection to control unit and batteries with supplied
cables
IP 30 (use only inside control unit or gearmotors or other protected environments)
