Features sine wave output in both AC mode or battery mode, can output high-quality sine wave power load to provide the best protection. Zero transition when the electricity is interrupted or restored, UPS switch between AC mode and battery mode is no conversion time, effectively ensuring the reliability of the load operation. Other brand rationalization bypass output line UPS when Bypass MODE, UPS can not protect the load straight, and Digital Series UPS in Bypass MODE when still provides automatic voltage regulator output, the load more secure. TVSS function that is TRANSIENT VOLTAGE SURGE SUPPRESS surge voltage protection. For FAX, TELEPHONE, MODEM, network conversion protection. DC start function at power cut state, if the need to use the UPS to start the computer or other loading equipment, Digital Series UPS is in battery mode can boot directly to make UPS more convenient and reliable. Bypass protection UPS bypass feature allows the emergency response capability has been greatly strengthened, when the user load equipment for the power of special requirements, such as voltage can not be too high, Digital Series UPS bypass supply voltage is too high protection to the user The load equipment from high voltage risk. Long-term power supply design Digital Series UPS offers a comprehensive long-term machine for users to choose. Configure the appropriate battery pack allows the UPS discharge time up to 8 hours or so, in order to meet the requirements of different grid environments. Digital Series UPS term machine in addition to extend the discharge time, charge the battery back strong ability to provide initial charging current of about 3 ~ 4A. Self Check Digital Series UPS can be simulated without power into the battery power mode, this function either through self-test button on the front panel to perform at any time to be with the complimentary monitoring software, according to a regular or irregular manner. It can be used with generators Wide input voltage and frequency range, making Digital Series UPS with mainstream brands with the use of a generator to extend the use of time, while effectively removing impure electricity produced by the generator for the load to provide a safe, stable power supply. Can be accessed by inductive load Digital Series UPS can be connected inductive load (PF≥0.8). Random monitoring software to enable users to UPS management more convenient and effective, were presented monitoring software, intelligent management. Equipped with intelligent slot Intelligent Slot Digital Series UPS is equipped with a smart Intelligent Slot slot, users can choose SNMP network card, centralized control and remote monitoring.
