Table 3.
Supply voltage
16V÷22V/AC (min. 50VA)
Supply frequency
50Hz (47÷53HZ)
PSU module power P
35W max.
Current consumption
3.3 A max.
Output voltage
11,0V÷13,8Vdc – buffer operation
10,0V÷13,8Vdc – battery assisted operation
Output voltage setting, escalation and keeping
time
20ms/40ms/12ms @ Inom., Uac=min.
Voltage setting range
11,5 V÷14,0 V
Voltage adjustment range
± 1%
Ripple voltage
25mV p-p max.
Output current
2,0 A max.
Current consumption by PSU module systems
25 mA max.
Battery charging current
500 mA max (@7Ah, U bat.=10,0V) or
* 200 mA max (@1,2Ah, U bat.=10,0V) (± 5%)
(* J dip switch function, version v.2.0 or higher)
SCP short-circuit protection
200% ÷ 250% of supply power – limitation of current and/or
fuse failure in the battery circuit (fuse-element replacement
required)
OLP overload protection
110% ÷ 150% (@25ºC÷55ºC) of power supply – current
limitation with the PTC automatic fuse, manual restart (the
fault requires the disconnection of the DC output circuit)
