Энергия связь 4-квадранта преобразователь частоты

Power rangeVoltage : 380V,690Vpower : 1100kW and belowApplication areaIt has been widly applied in in oil field, mine and cement industryMain featureIt can be mained applied in the belt convery which needs high reliability and maintenance requirments to inverters. SB70G main features are large starting torque, high power factors, energy feedback, loading auto-balance and modulization design. All protect functions are completed and SB70G has related special control functions.SB70G large power four-quadrants has excellent motor control function based on SB70 core vector control technology and Senlan special energy feedback technology. Adopting Dual-PWM control technology largey improve system power factors and realize AC motor four-quadrant running, which meet all kinds of potential energy regulating requirments. SB70G can transfer regenerated power of motor to electric power and feedback the power to network, which can reach maximum saving power. In addition, SB70G can reduce harmonic constamination to the network and the power factor can nearly reach 1 Adopt no touch point switches inside, Protect level reaches to IP50, anti-humidity, anti-corrode, suitable for outdoor tough environment.Complete protect and diagnose function, user friendly design, more parameters to be
