The QZ On-Line UPS (range from 1KVA ~ 40KVA) uses the most advanced PWM technology and double conversion topology to provide perfect power protection. Its unique AVR design can expand the input range from 160Vac ~ 300Vac. It is best employed in places that might experience utility power fluctuation. The expanded input range of the UPS will help reduce battery charge / discharge cycles thus extending the life of the battery. In addition, the QZ On-Line UPS Long Backup Series with built-in high capacity charger (10A) can rapidly recharge the external battery bank that will provide protection to the locations going through power utilization blackout.

The QZ On-Line UPS Series utilize microprocessor controller to replace traditional analog or digital components in its control circuit. The design not only increases the MTBF of the UPS, it also provides a precise and reliable output. Additional feature with the microprocessor controller will communicate with equipments/computers that are connected to the UPS via built-in RS232 or RS485 interface. By using the monitoring software, users can easily obtain the UPS status and it can also schedule the turn on/off function of the unit.

The clear and high contrast LCD Front Panel on the UPS provide users with instant and friendly access to the status and conditions of the UPS (such as input utility power, output voltage, load, fault and battery capacity) without operating the monitoring software. For ease of ownership, the QZ On-Line UPS can record up to 3996 steps of data for future references and check ups on the unit.
