¹ From the backup rechargeable battery after the loss of the main power supply.

Backup rechargeable battery capacity

up to 7 Ah with a full charge cycle of up to 30 hours²

When a 4 Ah rechargeable battery is used, the minimum operating time at a maximum load of 1.7 А is 2 hours. For autonomous operation for 12 or 24 hours, the maximum load should not exceed 0.3 A and 0.15 A, respectively.

When a 7 Ah rechargeable battery is used, the minimum operating time at a maximum load of 1.7 А is 4 hours. For autonomous operation for 12 or 24 hours, the maximum load should not exceed 0.4 A and 0.2 A, respectively.

² It is the maximum time to recharge a 7 Ah battery to 80% of its capacity.
