2
Features:
 DC 54V/5A* uninterruptible power supply
 outputs protected by 5A melting fuse
 wide range of mains supply AC: 176÷264V AC
 high efficiency 85%
 built-in power factor correction system (PFC)
 battery charging and maintenance control
 excessive discharging (UVP) protection
 battery output protection against short circuit and
reverse connection
 battery charge current: 0,5A
(batteries 4x7Ah / 4x17Ah)
 control of voltage presence at the outputs
 acoustic indication of failure
 LED optical indication: AC, DC, TEMP, LoB,
ALARM, AUX
 the ALARM technical output of collective failure
– relay type, activated by:
 230V AC power loss
 low voltage of the PSU (<46V)
 activation of the output fuse
 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
