Welcome to Shanghai Wenba Electric Co., Ltd.



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, WARD GOLD Series 1K, 2K, 3K UPS, tieds UPS, UPS battery backup are connected through the RS232 communication port to WARD Power Management software for power detection and power monitoring, to integrate UPS and the network server into one entity with power status available at any time. Moreover, it achieves the intelligent functions such as timer-controlled self-inspection, automatic disk-saving, automatic timer-controlled power-on and power-off and record of power status etc., to achieve the zero distance of communication between the user and UPS. Whenever utility power supply is interrupted, the UPS, tieds UPS, UPS battery backup will inform the server immediately and gets ready for switching off the unit and saving automatically all data before performing the normal power-off instruction. Even in an unattended network environment, the UPS can still ensure data safety of the network system.
