Three phases 440 volt 60hz to Three phases 400 volt 50hz converter

Product Description

Three phases 440 volt 60hz to Three phases 400 volt 50hz converterThree phases 440 volt 60hz to Three phases 400 volt 50hz converter is the most advanced AC to DC to AC type converter products, which is characterized by multi function, stable and reliable performance, set up parameters flexibly, easy for maintenance and long service life 15 to 20 years. It can meet different user different requirementsThree phases 440 volt 60hz to Three phases 400 volt 50hz converterAdvantages: Easy to repairAdopted Japanese Mitsubishi IPM intelligent module, Modular and simple structure design, very easy and convenient for maintenance, any fault only need us send you parts for replacement, maintenance is low skill work Little fault rateIt with powerful protection function for short circuit, over load and over temperature which is more safe and reliable. Fault rate < 1%100% full power stable outputInside with full power low frequency isolated transformer, 100% full power output, can work 24hx7, which ensure the AC busbar and DC busbar are completely isolated, the harmonic and interference is very little, constant voltage and constant frequency stable output. And the accuracy of output voltage is very high less than 1%.High efficiency> 92%Long service life> 15 yearsSetting flexibleThe output frequency 50Hz or 60Hz can be set.The output voltage can be set.Two kinds of start modeVariable Frequency Start or Step Down Voltage StartWith higher capacity to drive motor inductive load, save the cost of soft starterBig LCD displayDisplay real time running parameters, easy operationThree phases 440 volt 60hz to Three phases 400 volt 50hz converterSpecifications: AC InputAC input voltage: Three Phase 440Vac 60Hz(L1-L2-L3 440V)AC OutputAC output power: 3kw to 500kw avaliablePure sine wave400VACThree phase L1 + L2 + L3 + N + EarthFrequency 50 or 60 hzPower Factor: >0.95Inverter efficiency: >94%LCD DisplayVoltage accuracy: Load balancing<1%, Unbalance <5%THD: linear load, 2%, nonlinear load >3%No load amps: 2% of inverter size depending on DC voltage (1000 watts / DC input voltage = amps)ProtectionsOverload 150% for 5 seconds, 120% for 35 secondsInput reverse polarityUnder voltageOver voltageOutput over currentShort circuitOver temperatureFan cooled: Always onShort circuit: no automatic recovery.
