Online uninterruptible power system 30kVA

NET brand online low frequency ups precise-protects heavy industry site and important equipment.

High power ups: T 30kVA 40kVA for your best professional solution choice.

System advantage

5.7-inch blue-background TFT touch screen HMI display ups running modes with an analog flow-diagram clearly, easy operation,        good memory: 500 running parameters after ups off due to ac failure, very convenient management.

Advanced DSP achieves precise, speedy, reliable, safety and stable control.

ASIC/Application Specific Integrated Circuit) control tech

IGBT thyristor inverter kits balances well 3ph loads, Inverter output isolation transformer decreases harmonic distortion current to loads, minimizes interference from grid supply. IGBT-base rectifier of best performance and high reliability suppresses harmonic distortion pollution from grid effectively, enhancing input power factor,

Flexible 1+1, N+X parallel redundancy achieves best synchronization detection(phase angle difference<0.50 degree, adjust transiently loads active power and reactive power, attains precise load average, fault ups unit(inverter fault) auto retreat from parallel system other units continuous supply to load without interruption high quality sine wave power. Low parallel circulation and current imbalance<1%.

Online double conversion design DSP control & transient waveform control THDi<4%, high input power factor>0.99, low THDv <5%, very energy-saving and environment-friendly, Efficiency reaches 93% on normal mode, 96% on ECO mode. If current loads need not very high quality power(eg. Interruption<20ms), vendor can run ups on ECO-mode.

High reliability, High tolerance ability, strong anti-interference, strong over-load, anti-lightning, high rush-in  voltage and surge suppression, protection against Short circuit, input over-voltage, charge abnormal. Ups passed strict short-circuit test, 2000Vac high voltage insulation test before delivery.

Intelligent monitor slots: RS232, RS485 dry contact, inbuilt modem sot, battery test slot, optional inbuilt SNMP card, battery testing module. Optional battery testing module can monitor operation parameters of 160-cells one time via dual-direction communication intelligently. Scanning each battery block, test each cell in consequence transiently and precisely. Real time battery operation parameters and battery real-time remaining backup time data available via monitor slots. With battery remaining capacity and active material rate measured, battery test module locates damaged battery precisely and alarm with a signal, battery test module guarantees ups reliability. Battery average-charge and float-charge function extends battery service time. With battery’s manual/automatic discharge(built-in) activated, rectifier input voltage decreases to 382Vac(less than 384V battery nominal DC voltage) to execute automatic battery discharge test in case of unexpected critical load power-lost due to battery fault(ups transfer to bypass mode). AMB” management battery strings intelligently. Alarm and protection: built-in variety of alarm signal displays on HMI, indicates with LED indicators, or through audible beeper, or transit via dry contact in-lets and out-lets in time, precisely, specifically.

Delay soft-start minimize high power shock to other equipment and external grid source, Cold start: Battery discharge to feed inverter to supply loads when ac mains input fails. Ups auto-ON: When ac input power unavailable, battery discharge to continuously supply loads, ups will shut-down when battery discharged to EOD(End of Discharge).  Ups auto-on and runs on pre-set mode when ac recovers. Set ups function: With function setting completed, vendor may check 5 functional modules records of operation, alarm, communication.
