Product Overviews330

 

      Product overview

  • BD330 is the newest high-performance open-loop inverter based on DZB300. It has superior performance and rich functions with elegant appearance; heat dispersion is good, and the volume is smaller with a more reasonable design; the configuration is flexible that it can meet different demands of customers.

     Product features

  • Two control modes:non-PG vector control(SVC),V/F control
  • Multistage V/F curve setting function
  • Pull-in torque:non-PG vector control(SVC)0.5Hz could reach 150%
  • Internally installed PID control function that could implement close-loop constant temperature and constant voltage control.
  • Multiple frequency setting is supported:digital set, analog quantity set, PID set, RS485communication set.
  • Free programming is available for I/O terminal  and could combine various work patterns according to users’ need.
  • It’s equipped with control function of hopping frequency, and could actively suppress mechanical resonance to make system more stable and reliable.
  • It’s equipped with maintaining function in cases of instant power down so that it helps avoid influencing production caused by instant power down.
  • Detection function for torque rich and less torque.
  • Switch function of main and auxiliary frequency,  run command, and on the spot and long-distance.
  • Automatic voltage adjustment function that could effectively solve low frequency oscillation problem of high-power motor.
  • Provide protection functions for many malfunctions: omnibearing real time monitoring and protection of overcurrent, overvoltage, undervoltage, superheat, overload, phase loss to ensure safe running.
  • 0.75~15kW internally installed brake unit. It just needs to add a brake resistor to implement fast stop.
  • Higher than 7.5kW.  Internally installed trace function of revolving speed that could realize shock-free smooth start to the rotating motor.
  • Modular design that could be configured with various expansion cards.
  • 16 speeds. Time for each acceleration and deceleration is adjustable.

           

       Applications

  • Boiler fan, induced draft fan, exhaust blower underground coal mine.
  • Municipal engineering, energy conservation transformation for central air-conditioning.
  • Cyclone cluster, centrifugal fan, etc.
  • Circulating water pump, make-up pump, oil field injection pump, fuel delivery pump, music fountain.
  • Papermaking equipment, chemical industry, pharmaceutical industry, textile industry, etc.

      Technical parameters

  • Input voltage:1AC220V±15%  3AC220V±15%  3AC380V±15%   
  • Input frequency: 47~63Hz  power factor≥95%
  • Control mode:non-PG vector control and V/F control. Thereinto, V/F control is divided into three curves such as linear type, multipoint type and multiple power of two type.
  • Source of operation instruction:  given by panel, terminal and   RS485 communication
  • Source of given frequency:given by panel figure, analog quantity, RS485  serial communications, multi-speedsimple PLC and PID etc.
  • Overload capacity:type B :150% rated current 60s,180% rated current10s; type P 120% rated current 60s,150% rated current 10s
  • Pull-in torque:0.5Hz/150%(non-PG vector control(SVC)),range of speed 1:100(SVC),control accuracy of speed  : non-PG : ±0.5%.
  • Carrier frequency:1.0kHz~15.0kHz,and can be automatically adjusted according to temperature and load characteristic.
  • Frequency resolution:the given digital value is 0.01Hz,and the analog quantity is given as the highest frequency plus 0.1%.
  • Torque elevation:manual torque can elevate 0~30%.
  • Brake:DC braking when starting and closing down.
  • Inching operation:frequency range:0.0Hz~ maximum frequency of output,time  of inching acceleration and deceleration:0~3600.0s
  • Simple PLC and multi-speed operation:as many as 16 speeds operation can be realized through built-in PLC or controlling terminals.
  • Internally installed process PID:convenient for the realization of close-loop control of quantity of process (pressure, temperature, rate of flow);
  • Automatic voltage regulation:automatically keep the output voltage stable during voltage fluctuations.
  • DC bus can be shared by many inverters and the energy is balanced automatically.
  • Input and output terminal:6 digital input, 2 relay output, 1OC transistor output, 2 analog input, and 1 analog output.
  • LED can display set frequency, output frequency, output voltage, current output and other parameters.
