TBP Series Low Voltage Frequency Conversion Control Cabinet
Classification:
1. Overview
The TBP Series Low Voltage Frequency Conversion Control Cabinet is designed for three-phase asynchronous or synchronous speed regulation. It is a kind of speed control product which can change the speed of the motor by changing the supply frequency of the motor stator circuit. It is widely used in energy saving and speed control of fans and pumps in chemical industry, metallurgy, iron and steel, coal, cement and other industries.
2. Performance Features
◆ Large adjustment range, speed regulation ratio up to 20:1, high speed regulation accuracy;
◆ Energy saving effect is remarkable, the power saving rate is more than 30%, especially for variable load motors such as centrifugal fans and axial fans;
◆ With overload, lack of phase, undervoltage, three-phase unbalanced tripping and other protection functions to protect the safe operation of the motor;
◆ With serial communication interface, variable-frequency drive can be connected to remote control system.
