Intelligent microprocessor control
The product is an advanced on-line UPS based on dual-microprocessor control. This means
that it operates with the newest technology, high performance and powerful function.
The on-line UPS is an intelligent protector and provides pure, reliable AC power to the critical
loads - protecting them from utility power blackout, swells, sags, surges and interference.
The loads could include sensitively medical instruments, computers, telecommunication
systems, and industrially automatic equipment. Under power normal condition, the on-line
design enables the system to adjust and filter power fluctuations continuously and
automatically. In the event of power failure, it can provide immediate back-up power from
the batteries without any interruption. When overload or UPS malfunction, the system will
automatically transfer into bypass mode and keep supplying output equipment with utility
power; if overload situation is relieved, it will automatically transfer back to inverter mode
when malfunction is resolved by restarting the UPS. Complete transference will be achieved
within 4m seconds, with no interruption.
Beside this, when the utility power is connected, the charger would work automatically even
under power switch is OFF. Furthermore, in order to save the battery energy, UPS can
automatically turn it off under backup mode if none of the connected loads is operating.
Advanced battery management
The visual and audible indications of the UPS present the battery’s status including capacity
degree and battery condition. Self-test function let UPS detect a weak battery before it is put
into service. The UPS normally perform a self-test at power up and manual self-test condition.
Self-test function can be conducted manually with the ON/TEST switch at any time.
