PSU type A, protection class 1
÷3, II environmental class
Mains supply
230V AC 50Hz (-15%/+10%)
Current consumption 0,45 A
PSU’s power
61 W
Efficiency 81%
Output voltage
22 V÷ 27,6V DC – buffer operation
2
0 V÷ 27,6V DC – battery-assisted operation
Output current - for grades 1, 2:
Io = 0,58A + 1,5A battery charging
- for grade 3:
Io = 0,23A + 1,5A battery charging - (connection with
ARC required, compliant with 9.2
– EN 50131-1)
Io = 0,116A + 1,5A battery charging
- for general use:
Io = 2A + 0,2A battery charging
Io = 1,6A + 0,6A battery charging
Io = 1,2A + 1A battery charging
Io = 0,7A + 1,5A battery charging
Output voltage adjustment range
24 V÷ 29 V
Ripple voltage 60 mV p-p max.
Current consumption by the PSU systems
during battery-assisted operation I = 26 mA
I = 17 mA
– LCD panel backlight OFF
Battery charging current
0,2A / 0,6A/1A/1,5A
– I
BAT
jumper selectable
Low battery voltage indication
