Ranging: industrial grade10VA-50KVA
Features:
Complete power protection from an on-line double conversion design incorporating an automatic static bypass for overload and fault conditions.
Low running cists with a high operating efficiency.
Wide input voltage range to minimize batter consumption and so help extend battery life.
Full microprocessor management: comprehensive checkup and manage the data of UPS, ensure there is no disturbance to inferior load when the switch between power supply by bypass and power supply by inverter, while the UPS is fault, the microprocessor send out a signal, it can change to the bypass and supply with the power supply uninterruptedly, and provide with sound and light alarm.
Advanced automatic change and charge technology of constant current and voltage, activate the batteries furthest, together with strong charging current, expansion pile without adscititious charger.
LCD check-up the data in whole process: display the state of UPS, setup some parameter of UPS on the panel, feedback all signals check-upped by microprocessor.
Powerful overload ability: 125% load is 5 min and 150% load is 30 s.
Intelligent temperature control fans, reduce noise, RS232 ports, provide with intelligent monitor software, various operating position can be changed to contact surface signal, and output.
Control teleswitch and battery testing online. RS485 ports which can supply with telemonitoring panel extend to 1200m(options).
Manual maintenance bypass SWMB, achieve online service.
Automatic fault check-up system: check-up fault of UPS automatically, and can be displayed on LCD straight, so help service staff remove fault expediently and fleetly.
Perfect protection function, possess the protection of AC input over voltage/under voltage; the protection of uptput over voltage/under voltage; the protection of over load output, shout, inverter and rectifier over temperature, under voltage pre alarm, batter over charge etc. ensure the system can run stability and reliability.
