Variable frequency Vector Sensorless Inverter

About Bedford

Guangzhou Bedford Electric Equipment Co., Ltd. has focused on automatic water pump controllers and solar pump inverters since 2003. We aim to provide users with innovative inverter solutions for stable water supply systems worldwide. It is essential to source quality automatic water pump controllers from a reliable water pump manufacturer to improve the automation level of water supply systems and reduce equipment maintenance and labor costs.

 
B503D Series
 
Product Brief
B503D series vector inverter  adopts DSP control system which supplies Sensorless Vector Control (SVC) and V/F control. Comparing with V/F control ,the performance of DSP has greater superiority, which consists of inbuilt SVC and V/F control accuracy, it is widely applied to high speed control accuracy, rapid torque response and high performance at low frequency.
 
 
Main Control Function
 
Control Mode :Sensorless Vector Control (SVC),V/F Control
