2
Features:
 DC 54V/12x0,3A 48V uninterruptible power supply
for powering 12 IP cameras (15,4W / channel)
 DC 12V/4A uninterruptible power supply for powering
of the recorder
 12 outputs independently protected by 0,5A polymer
fuses PTC
 the recorder output is protected with a 5A PCT polymer fuse
 wide range of mains supply AC: 176÷264V AC
 built-in power factor correction system (PFC)
 high efficiency 82%
 battery charging and maintenance control
 excessive discharging (UVP) protection
 battery output protection against short circuit and reverse
connection
 designed for 10Mbit/s and 100Mbit/s network
 acoustic indication of failure
 battery charge current: 0,5A
(batteries 4×7Ah / 4×17Ah)
 Approximate backup time: 8h 15min
 LED optical indication: AC, DC, LoB, TEMP, ALARM,
NVR
 control of voltage presence at the PoE outputs
 power over pairs: 4/5(+), 7/8(-)
 the ALARM technical output of collective failure
– relay type, activated by:
 230V AC power loss
 low battery voltage (<46V)
 activation of the output fuse in the camera
power supply circuit
 activation of the output fuse in the recorder
 power supply circuit too high temperature of the
PSU (>70°C)
 the PSU failure
 protections:
 SCP short-circuit protection
 OVP overvoltage protection
 overvoltage protection
 overload protection OLP
 forced cooling (fan)
 warranty – 2 year from the production date
