Calculate panel power consumption needs power consumption of each module, calculate heat generation and temperature rise.
Determine the power consumption of each module:
First, the power consumption of each module needs to be calculated.
For example, the average power consumption of an input module can be calculated using the formula Win = Iin * E / Input points Simultaneous ON.
where Iin is the input current, E is the input voltage, and Input points Simultaneous ON is the number of input points turned on simultaneously.
For the external power supply part of special function modules.
Its power consumption can be calculated by the formula WS = I15V * 5 + I24V* 24 + I100V * 100.
Where I15V, I24V, and I100V are the current consumption under different voltages, respectively.
Calculate heat generation and temperature rise inside the control panel:
Based on the total power consumption W.
The temperature rise inside the control panel can be calculated using the simplified equation T = W / UA.
Where UA is the thermal conductivity of the control panel.
By following these steps, the power consumption of the control panel of an injection molding machine can be estimated more accurately and its environmental impact and cost can be further assessed.
This approach is not only applicable to specific injection molding machines but the model can also be optimized and improved by benchmarking and experimental measurements for different types of machines and technologies.
Individual module of Calculate panel power consumption
- Power supply module power consumption
- DC5V circuit power consumption
- DC24V circuit power consumption
- Special Function Module Power Consumption
- Overall PLC System Power Consumption
Power supply module power consumption:
Power supply modules usually convert the external input voltage into the DC voltage required by the PLC system, e.g. 24 V DC.
Different types of power supply modules have different output power.
For example, the power supply modules of the S7-1500 series have specifications such as PS 25W and PS 60W.
When selecting a power supply module, its rated output power must be greater than the total power consumption of all modules, with a margin of about 30%.
DC5V circuit power consumption:
The total power consumption of the DC5V circuit is equal to the sum of the power consumption of each module.
This should calculated as W5V = I5V × 5 (W), where I5V is the current consumption of the DC5V circuit.
DC24V circuit power consumption:
The average power consumption of the DC24V circuit is also equal to the sum of the power consumption of each module.
We calculated as W24V = I24V × 24 (W), where I24V is the current consumption of the DC24V circuit.
Special Function Module Power Consumption:
The power consumption of special function modules usually includes the sum of the power consumption of multiple modules.
This one calculated as Ws = I+15V × 5 + I-15V × 15 + I24V × 24 (W), where I+15V, I-15V and I24V are the currents of +15V, -15V and 24V respectively.
Overall PLC System Power Consumption:
The total power consumption of the overall PLC system is the sum of the power consumption of each part and is calculated as W = WPW + W5V + W24V + Wout + Win + Ws (W).
With these formulas, the total power consumption of the PLC system can be accurately assessed and the thermal design can be carried out as needed to ensure stable operation of the system.
