It uses 32B 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. Under normal conditions, it provides network system with power protection for virtually zero interruption, regulated voltage and regulated frequency, interference-resistant capability and filtered noisy signals. The main power obtains DC bus voltage via AC-DC circuit, which is then converted to 220V AC output via the inverter, so as to safeguard data over the entire network. Therefore, the power used by load is purified sine wave power via regulated voltage and regulated frequency with noisy signals filtered. Furthermore, this product can be connected through RS232 communication port to Upsilon2000 power management software for power detection and power monitoring, to integrate UPS and network server into one entity with power status available at any time. Moreover, it achieves intelligent functions such as timer-controlled self-inspection, automatic disk-saving, automatic timer-controlled power-on and power-off and record of power status, to achieve zero distance of communication between user and UPS. Whenever utility power supply is interrupted, UPS 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, UPS can ensure data safety. producing area:China payment:T/T, L/C supplying capacity:100pcs/day
