QZ Series15KVA / 12KW Low Frequency Single Phase Online UPS

QZ Series15KVA / 12KW Low Frequency Single Phase Online UPS

QZ series use the advanced PWM and IGBT inverted technology, capable of precisely controlling all kinds of operation parameters of the UPS, therefore they can provide a high quality and reliable AC power source for your precise equipments. With their unique AVR design that expands the input range, the QZ series are very suitable for harsh environment, reduce battery charge/discharge times, thus extend battery life. Besides, the long backup UPS with large built-in charger (10A) can rapidly recharge external battery so as to provide perfect protection for long blackout.

QZ series utilize microprocessor control to replace traditional analog or digital components in its control board. The design not only increases the MTBF but also provides a precise and reliable output. With proven field experience all over the world, the QZ series provide an optimum choice for complete protection solution from micro computers to large scaled computers, from communication systems to industrial automatic control equipments.
