would be turned on automatically.
●
Via internal or external SNMP card, UPS can go on internet, you can monitor and manage the UPS status
through all kinds of network management system.
1.2. System and model description
H online series is an uninterruptible power supply incorporating double-conversion technology. It provides
perfect protection specifically for computer equipment communication systems to computerized instruments.
Its true online double-conversion design eliminates all mains power disturbances. A rectifier converts the
alternating current from the utility power to direct current. This direct current charges the batteries and
powers the inverter. On the basis of this DC voltage, the inverter generates a pure sinusoidal AC voltage,
which is constantly powering the loads.
Computers and peripherals are thus powered entirely by the UPS. In the event of power failure, the
maintenance-free batteries power the inverter.
This manual is applicable to the following models:
1) H1KS, H2KS, H3KS are standard models with inbuilt battery.
2) H1KL, H2KL, H3KL are long backup time models, which are able to connect with the external battery
bank.
