PROTECTION DEVICES INCORPORATED IN THE POWER SUPPLY UNIT
Overload protection
The UPS indicates an overload for a load in excess of 110% of the UPS rated power.
This is signalled only in battery mode. The UPS:
switches off after 30 seconds in the range 200-400 W
switches off within 5 seconds above 400 W
The diode on the front panel starts to flash rapidly, while the sound signal becomes
intermittent.
Short circuit protection
The power supply unit is equipped with a fusible cut-out on the mains input and an
electronic fuse on the output. The electronic fuse operates only in battery mode.
Activation of the electronic fuse is indicated by the rapid flashing of the diode. A short
circuit is also signalled by a very quick, intermittent sound. Because the battery is
connected externally (it is not built-in), additional protection devices have been
utilised:
a. Battery overvoltage protection
The power supply unit is protected against the connection of a battery with a voltage
greater than nominal. In this case, the car fusible cut-out will burn out.
b. Protection against an incorrect battery connection
The power supply unit is protected against reverse battery connection.
NOTE!
In the event of activation of the overvoltage protection or reverse
battery polarisation, the burn-out of the UNIVAL fuse will be
accompanied by damage to the protective diode. In this case, please
contact the manufacturer’s service department for replacement.
Battery overcurrent protection
The power supply unit is protected against exceeding the maximum battery current
by two protection devices:
- electronic
- car fuse, UNIVAL type, 19 mm, 40 A.
