Advanced DSP digital control technology The inverter control, phase synchronous, I/P rectify control, logic control systems all take advantage of the DSP technology so that the UPS has the following features: High precision, high speed, simplified control circuit and high reliability High input power factors: The I/P power factor is above 0.98 Input current THDI <5%, which greatly reduces the pollution of the AC network and the efficiency of the usage of the utility is improved and the installation cost and the noise is reduced Wide input voltage and frequency range, it reduces the frequency of battery discharge so that the battery life can be prolonged and in the meantime, it can works with oil generator It adopts the most advanced parallel control technology and digital equal flow control technology to make the UPS highly compatible and have the choice of N + 1 parallel and redundancy and share battery sets Abundant interface setting functions: The user can set the O/P voltage and frequency through the front panel buttons and the UPS can be set to connect equipment with different voltages and frequencies Flexible network monitoring and management The UPS is available with RS232, USB, EPO, RS485 (optional), SNMP (optional), dry contact (optional) and so on It can supports TCP/IP protocol with remote control The network monitoring and management enables the UPS to have the function of self-diagnosis, timingly sending the demanding instruction, email, automatically saving the files and turning off the UPS Large LCD display in both Chinese and English languages Perfect protection: UPS has I/P and O/P over-voltage protection, low voltage protection, overload protection, short-circuit protection, over-heat protection, surge protection and so on Cold start and AC start without battery
