Designing Energy-Efficient Control Panels: Tips and Best Practices

Written by Peter Sowerby | Feb 18, 2025 9:23:38 AM

Control panels are an essential part of any industrial operation.

They are responsible for controlling and monitoring the various processes that make up a manufacturing or production line. As such, they can be a significant source of energy consumption. In recent years, there has been a growing focus on energy efficiency in all aspects of industrial operations, and control panels are no exception. By designing energy efficient control panels, businesses can save money on their energy bills and reduce their environmental impact.

There are a few factors to consider when designing energy efficient control panels.

Component Selection

The components used in control panels can have a significant impact on energy consumption. For example, some types of relays and contactors consume more energy than others. When selecting components for control panels, it is important to choose those that are energy efficient.

The calculation for power consumption is P=V2/R where (P)ower is the Energy used in Watts, (V)oltage & (R)esistance of the coil.

By selecting a relay with a lower voltage consumption (12V rather than 24V) it reduces the Power usage.

Panel Layout

The layout of the components in a control panel can also affect energy consumption. By arranging the components in an efficient manner, it is possible to reduce the amount of energy that is wasted. By ensuring components are placed in an efficient manor you not only reduce the power requirements to more the energy around, but you also have the added benefits of reducing cabling and therefore costs as well.

Cooling

A side effect of energy is heat. & control panels generate heat, this heat can be wasted if it is not properly managed. By using efficient cooling systems, it is possible to reduce the amount of energy that is used to cool the control panel. Once again if the control panel is created efficiently, this has a knock-on effect of reducing heat & therefore reducing the amount of cooling needed to combat the heat outputs.

Software

The software that is used to control the panel can also affect energy consumption. By using efficient software, it is possible to reduce the amount of energy that is used to operate the panel.

In addition to these factors, there are several other things that can be done to improve the energy efficiency of control panels. These include:

  • Using energy efficient lighting: By using energy efficient lighting, it is possible to reduce the amount of energy that is used to light the control panel. For example, the switch from lamps to LED indicators.
  • Using variable speed drives: Variable speed drives can be used to control the speed of motors. This can help to reduce the amount of energy that is used to operate the motors.
  • Using power monitoring systems: Power monitoring systems can be used to track the energy consumption of control panels. This information can be used to identify areas where energy can be saved.

By taking these factors into consideration, it is possible to design energy efficient control panels that can save businesses money and reduce their environmental impact.

Benefits of Energy Efficient Control Panels
There are several benefits to using energy efficient control panels. These include:

  • Reduced energy costs: Energy efficient control panels can help businesses to save money on their energy bills.
  • Reduced environmental impact: By reducing energy consumption, businesses can reduce their environmental impact.
  • Improved reliability: Energy efficient control panels are often more reliable than traditional control panels.

Conclusion

Energy efficiency is an important consideration for all aspects of industrial operations, and control panels are no exception. By designing energy efficient control panels, businesses can save money, reduce their environmental impact, and improve the reliability and safety of their operations.
