Product

DZB300 series high-performance vector inverter adopts DSP control system to complete the optimized speed sensorless vector control and V/F control, with richer functions, more flexible application and more stable performance.

Applications：

• Metal processing, CNC machine tools, wire drawing machines, and other mechanical equipment 
• Municipal engineering, central air conditioning energy-saving transformation
• Papermaking equipment, chemical industry, pharmaceutical industry, textile industry,etc.
• Various fan and pump loads

• Provide multiple fault protection functions: over current, over voltage, under voltage, overheat, phase loss, overload, etc 
• Two-speed control modes:  Vector control without PG(SVC)  V/F control mode
• 8-stage simple PLC, multi-stage speed control and PID control 
• Input and output terminals are free to program, and users can combine multiple working modes according to their needs
• 0.75~15KW built-in braking units of various specifications can connect the braking resistor directly if need to stop quickly.
• Support many frequency setting modes: digital setting, analog setting, PID setting, communication setting
• Starting torque  Vector control without PG: 0.5Hz/150%(SVC)
• With instantaneous power-off and non-stop function 
• The inverter above 37KW has a built-in DC reactor to improve the input side power factor and the efficiency and stability of the whole machine
