Double Conversion on-Line Low Frequency 20kVA Three Phase UPS

Main characteristicsDual static switch By 12 SCR (silicon controlled rectifier) near the inverter side and roadside dual non-contact static switch, to ensure that the inverter power supply and th e bypass uninterrupted switch between power supply, and make sure the output voltage waveform is continuous an d smooth.Control circuit adopted a "zero" switching technology, ensures the UPS in synchronous phase lock switch time 0 ms, out of sync with power grid, switching time is less than 4 ms, no matter how to change, name ly the gri d frequency all can ensure the UPS output voltage, frequency stability and uninterrupted.Self diagnose and self protectionPMUG series UPS has extremely strong self-diagnosis function, the whole machine set up 32 sensors, point to point with DSP detection and response of the ultra-high speed, makes PMUG series UPS self protection function is perfect, as many as 200 of the fault information prompt, and equipment parameters setting, real-time information data record diagnostic function to protect the UPS into the state in time, in addition, the machine is special equipment for emergency shutdown system is designed.Rechargeable battery intelligent managementCan automatically adjust the 1 a - 50 - a large current charger, battery since the diagnosis an d maintenance system, since the choice of the battery maintenance mode, the battery automatic alarm system, battery regularly circulation system, selection of no-load protection Settings, etc.Strong English display interfaceUsing full digital tou ch screen LCD display in both English and Chinese, display content can select the Chinese/English set, running state, operating procedures, data collection an d trouble shooting information at a glance.Double transformation is on-line designUsing DSP digital control technique, the UPS control precision, fast, reliable, stable and have perfect protection function and high reliability;Output waveform distortion is small.Flexible weaver technologySuitable for different load and system, can be stand-alone, 1 + 1 run weaver, also can be more machine (N + 1) we aver.System with high efficiencyUsing ECO work mode, efficiency is as high as 98% above.Technical Parametersmodel:PMUG10KVA15KVA20KVA30KVA40KVA60KVA80KVA100KVA120KVA150KVA200KVA300KVA400KVANominalcapacity(KVA)10152030406080100120150200300400Singe-phase   maximum current input(A)1929385776114152189227303379568609Works   as well as the principleOn-line   power supply,static bypass switch(uninterrupted switch)double conversion   technologyAc input parametersNumber   of phaseThree-phase+N+GNominal voltage380VAC±25%Nominal frequency50Hz±10%,60Hz±10%The voltage harmonic distortion
