Low Frequency Online UPS (Uninterrupted Power Supply) WZZ

Applications of Low Frequency Online UPS (Uninterrupted Power Supply):
Our low frequency online UPS are widely used to protect computer and peripheraldevices, date centers, telecommunications facilities, medical equipments, firefighting lighting and many other electrical equipments where an unexpectedpower disruption could cause serious business disruption or data loss etc.;

Features of LowFrequency Online UPS (Uninterrupted Power Supply):
1. High quality electric power supply: IGBT 20KHz SPWM modulate; over 340control points for each cycle wave;
2. Short circuit protection is available in our low frequency online UPS;
3. Parallel balanced current technology is adopted to enhance the performancereliability of our uninterrupted power supply;
4. On-line mode battery testing: we can test the battery quality when the UPSis power on;
5. 500 times of electric power supply abnormality can be memorized; and ifconnected with computers, more power supply abnormality can be recorded forconvenient maintenance and repairing. And the abnormality record could also besent out through emails.
6. 100% unbalance protection design: WZZ series low frequency online UPS canwork normally under phase loss conditions; and the output voltage stability is±1%;
7. Intelligent battery charging and management: floating charging and equalizedcharging are both available; alternative type constant voltage and constantcurrent intelligent management system is available to protect the battery andprolong battery life.
8. Digitalized CPU control: several modules of microprocessors are adopted todrive the system directly and as a result simplified the analog line; and theCPU load utilization, voltage and current utilization etc. can be calculated.
9. Dry contact signal, monitoring panel signal, RS-232 to RS-485 or RS-442signals are all available in this electric power supply product.
10. Communication interface is equipped, so out uninterrupted power supply canbe linked to computer and realize remote monitoring through internet.
