Introduction
Specification
Physical & Electrical

The VB series high-performance frequency inverters use the international mainstream 32-bit DSP as the main control chip. It has fast calculation speed, high control accuracy, and powerful control performance. Using well-known brand power devices and raw materials, processed with advanced manufacturing technology to meet the high-quality needs of our customers.


Maximum Output Frequency Improved

SVC Control Mode: Maximum Output Frequency 320Hz

VF Control Mode: Maximum Output Frequency 1000Hz

A maximum output frequency of 1000Hz in VF control mode can meet 

various speed control demands from customers Flow Chart of GND Short-circuit Detection

Excellent Braking Function

【Over-excitation Braking Function】 

The over-excitation braking function can help with a prompt braking action even without the braking unit on some occasions.

【Dynamic Braking Function】 

The braking torque could be higher and braking time shorter if working with a braking resistor. 

The 0.75-22KW models are designed with built-in braking units.

(Remarks) The braking performance varies from motor characteristics and load conditions.


Superior Control Performance

The improved low frequency and high torque quick- starting performance brings a faster response speed and a higher production efficiency The probability 

of equipment failure and shutdown can be reduced effectively with the enhanced current suppression algorithmso as to ensure a more stable processing capacity of the equipment.

Random Carrier Function

Noise Reduction

The random carrier function helps reduce the noise of the equipment so as to improve the environmental comfort.
