BD331 - inverters for water supply

The BD331 series inverters are high-performance solution for water pressure pump systems.Those inverters are specially made for factory and municipal water supply networks. The control algorithm, implemented on a DSP, allows to maintain stable water pressure and optimize pump loads.

Features:

  • Non-PG vector control(SVC), U/f control,
  • With SVC regulation  starting torque at 0,5Hz can reach up to 150%,
  • Multi-speed mode, PID regulation,
  • Multiple protections: overcurrent, overvoltage, undervoltage, overheating, overload, fire protection etc.,
  • Single- or multiple-pump operation.

Available models:

  • Power supply: 1AC 220V ±15%, Power: 0,5kW~93kW
  • Power supply: 3AC 380V ±15%, Power: 0,75kW~315kW

BD332 - inverters for injection machines

The BD332 series is a new generation of inverters dedicated for injection machines. The electronic part is based on a DSP. The inverter’s construction allows for it to be installed in high-temperature environments. The device can have an optional energy meter installed.

Features:

  • High overload capacity: up to 30s operation with 200% of rated current,
  • Frequency curve tracking,
  • High torque at low speed,
