approx. - 0.2 V
Output voltage
for buffer mode
27 V DC (no-load); 24 V (50 % rated battery current);
22 V (100 % rated battery current); 18.5 V (deep discharge protection)
Power-up characteristics Start delay < 1 s
Typical voltage increase: < 60 ms
Output +BAT/-BAT for nor-
mal operation
• Remark
I-U charging characteristic (initially fast charge current, then charge retention).
For one connected battery module the max. charge current is 0.3C A, for several battery
modules connected in parallel, the charge current is 0.3C A multiplied by the number of
batteries connected in parallel, however, limited by the maximum permissible charge cur-

Output current – rated value
• Remark
When using the UPS1100 5 Ah, Extra Power is permissible for 1 s/min.
Charge current Max. 3 A
Automatic setting for
UPS1100; otherwise 0.3 A,
0.8 A or 3 A can be selected
(by software or jumper (see
Table 2-5 Charge current
(Page 29)))
Max. 4 A
Automatic setting for
UPS1100; otherwise 0.8 A,
1.75 A, 4 A can be selected
(by software or jumper (see
Table 2-5 Charge current
(Page 29)))
Max. 5 A
Automatic setting for
UPS1100; otherwise 0.8 A,
1.75 A, 4 A can be selected
(by software or jumper (see
Table 2-5 Charge current
(Page 29)))
• Remark
The charge current can be automatically reduced if the charge current plus the load current
at the UPS1600 results in an overload of the feeding power supply.
The charge current can also be reduced if the ambient temperature of the UPS1600 is
higher than 40 °C - or if the input voltage at the UPS1600 is less than 24 V.
Derating:
10 A: 3 A→2 A
20 A: 4 A→3 A
