Power switching and protection
Inverter panels are usually designed with a circuit breaker connected to the input line power supply to turn the panel on/off and provide protection against short circuits or overloads in circuits and variable speed drives. In addition, inverter panels can cut off power to ensure operator safety during motor maintenance. Adjustable speed
A frequency control potentiometer is installed on the cover of the inverter panel to transmit command signals to the motor according to the value set by the operator. The inverter board has a network switching function to ensure the continued operation of the system in case of drive failure. Visual control
The inverter panel has a screen and a function panel in the front body, which is connected to the electrical components inside the control panel. This theorem makes it visually display the operating status of the board and is suitable for controlling the engine operator in real field operations. Safety protection
Placing the drive integrates all other electrical components inside the inverter board, thus reducing the impact of the external environment on the electrical components and ensuring the safety level of the operator such as reducing the risk of shock, so it has a better safety protection function. Components inside an inverter control board
There are many components that you can put inside an inverter control panel. Here are some examples of what you might find: Inverter
The main component of the engine control panel. VFDs vary in voltage, horsepower, full load amps (FLA), and other specifications. Sometimes you may find additional inverters installed (to be used in case the main inverter fails).
NEMA Rating
The housing of a control panel is rated for different resistance levels. This standard was created by the National Electrical Manufacturers Association (NEMA). Below are some common campus rankings: NEMA 1 - General Purpose, for indoor use NEMA 3R - Weatherproof, for outdoor use NEMA 4 - Protection against falling dirt, rain, snow, dust, wind, splashing water NEMA 4X - Protects against falling dirt, rain, snow, snow, dust, wind, splashing water and is also corrosion resistant.
