Product Description

Product overview

The series of BD 331 high-performance specialized inverter for constant pressure water supply is designed for the constant pressure water supply of factories, communities, and municipal construction. It uses 32 bit DSP all-digital control system and international leading vector control algorithm, and realizes load driver control of high-performance PID and high-accuracy pumps. It enhances the usability of customers and industrial professional design when improving the reliability of products and environmental suitability. The functions are optimized, and the applications are more flexible, as well as the performance is more stable.

Product features

Two speed control modes: non-PG vector control (SVC), V/F control
Non-PG vector control (SVC), pull-in torque: 0.5Hz could reach 150%.
8 speeds simple PLC function, multi speeds control and PID control
It supports setting of various frequency: digital setting, analog quantity setting, PID setting, RS485 communication setting.
  I/O  terminal is free to be compiled. Many work patterns can be combined by users according to demands.
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.
Inspection function for torque rich.
Provide protection functions for many malfunctions: omnibearing real time monitoring and protection of overcurrent, overvoltage, undervoltage, superheat, overload, phase loss to ensure safe running.
Reaching high pressure inspection, reaching low pressure inspection, sleep/revival function, water shortage warning function, routing inspection of fire protection function, etc.
Many control modes: Control functions of single pump mode and multi-pumps mode can be realized.
Timing alternate control to effectively avoid rust of pump.
