UNINTERUPTIBLE POWER SUPPLY

Also, if the consumers that are connected to the UPS will exceed the
maximum power by 110%, the UPS will emit an intermittent acoustic
signal and will automatically close. In case of inductive consumers
like water pumps or electric motors it is recommended to use a
power consumer up to 50% of maximum power of the UPS because
inductive consumers may need a double value of power at start.
ATTENTION! ELECRIC SHOCK HAZARD!
During operation, you must not touch the battery terminals.
To stop the UPS hold the ON/OFF button for 4 seconds until the UPS
emits an acoustic signal and stops.
To extend the battery life it is recommended that you do a cycle of
empty and full charge the battery, at least once in 2 months. Perform
this task if in this period of 2 months were no power failures and the
battery has been kept full all the time.
MAIN FEATURES
Protection features:
- Thermal: if the UPS is heating up the cooling fan is automatically
controlled according to UPS needs, (you don’t need to worry if you
hear the fan working even if the battery is fully charged or there is no
power consumption, the fan is automatically switched on and off
depending on the UPS needs).
- Ground: The UPS stops if there is leakage current.
- Battery (alarm and protection) if the battery is discharged to a
value of 10,8V the UPS will cut off the power to prevent the
destruction of the battery. A fast alarm sound will signalize this.
- Overload protection: if the UPS load exceeds by 110% the rated
power the UPS will stop to avoid own destruction.
- Short circuit protection: the UPS stops in case of short circuit.
- Voltage regulator (AVR) provides a constant voltage to consumers
in a given interval.
- Switch on the battery: the system switches on the battery if the
main power supply disappears, providing uninterrupted power to the
consumers.
- Bypass function: if the electric motor requires more power to start,
when the system can, it will supplement the necessary difference.
- Microprocessor: all functions are supported by a high frequency
