In line with the power requirements for network system, EAST has developed a new generation of true on-line intelligent UPS -- EA900 series.
It adopts 32 bits data-bus microprocessor with robust processing power that is capable of detecting and controlling quickly and accurately all
movements of UPS to ensure high reliability. Owe to the use of the double-conversion circuit design, the power used by load is the pure sine
wave power by stabilizing voltage and stabilizing frequency and noisy signals filter.
Furthermore, EA900 series UPS and the network server are connected together through the RS232 communication port and power monitoring
software, which offers power status available at any time. Moreover, it achieves the intelligent functions such time self-inspection, automatic
disk-saving, automatic time switch ON/OFF and automatic power status recordation, etc, so it achieves the zero distance of communication
between user and UPS. When main power is disconnected, UPS informs the server immediately and gets ready to be switched off and
automatically saves all data before performing the normal switch-off instruction. Even in an unattended network environment, UPS can ensure
data safety of the network system.
