Definition:

UNITROL 1020 3BHE037460R6207 High voltage inverter is a power control device that uses the on-off action of power semiconductor devices to convert the power frequency power supply to another frequency. It is able to convert a fixed frequency and voltage power input into an adjustable frequency and voltage output, thus achieving precise control of motor speed and torque.

How it works:

UNITROL 1020 3BHE037460R6207 The working principle of the high voltage inverter mainly includes the process of rectification, filtering, inverter and control.

Rectifier: Converts the input AC power to DC power.

Filter: Reduce the pulsation amplitude in the DC to make the DC more stable.

Inverter: Converts the filtered direct current into alternating current with adjustable frequency and voltage.

Control: The control system monitors the running status of the power supply and the motor in real time to ensure the stable operation of the high voltage inverter, and adjusts the output frequency and voltage according to user needs.

Advantages:

Large speed range, high precision: can be used for high precision, good speed performance occasions.

Energy saving: UNITROL 1020 3BHE037460R6207 Controls the load at the appropriate operating frequency to improve efficiency and reduce energy consumption.

Mature technology: there are many internal electronic components and complex lines, but technically more and more mature and reliable.

Improve the power factor of the grid: Without power compensation, it can improve the power factor of the grid and reduce reactive power loss and line loss.

Cons:

Technical complexity: there are many internal electronic components, complex lines, and maintenance requires more professional technical operation and maintenance personnel.

High cost: Compared with low-voltage inverter and traditional motor control device, the production cost is higher, and the sales price is also high.
