Following the popularity of computer networks and the continual upgrades of information processing technology, there is now virtually no limits for network information transmissions. Undoubtedly, the server is the soul of a computer network which processes numerous network data day in and day out and is naturally more demanding in terms of power requirements computers in general. Any increase of power network load, excessively low voltage, unstable frequency or even a sudden power-off can interrupt normal network operations!
In line with the power requirements for network system, WARD has developed a new generation of on-line intelligent UPS, tieds UPS, UPS battery backup---GOLD Series 1K, 2K, 3K UPS. Its uses the Motorola microprocessor with robust processing power which is capable of detecting and controlling quickly and accurately all movements of the UPS to ensure high product reliability. In addition to providing the network with power protection for virtually zero interruption, regulated voltage and regulated frequency, interference-resistant capability and filtering of noisy signals, under normal conditions, utility power obtains via AC-DC circuit the DC bus voltage which is then converted to 220V AC output via the inverter, so as to safeguard the data over the entire network. Therefore, the power used by the load is the purified sine wave power via regulated voltage and regulated frequency with noisy signals filtered. Furthermore,
