What is the power consumption of a laser machine?
The power consumption of a laser machine
Influencing factors for power consumption
The total power consumption of a laser system depends on these factors.
1. Actual working time
This is the amount of time the laser takes to perform an engraving or cutting process. In practice, 20 to 50% of the working time is spent on preparation, loading and unloading of the laser. During this time, Trotec lasers are on standby and only require minimal power thanks to their energy-saving function.
2. Used laser power
Depending on the machine, the laser has a maximum power, e.g. a 20-watt laser differs significantly from a 100-watt laser. In addition, the maximum laser power is only used for a sub-range of all laser jobs.
3. Peripheral equipment
Using an exhaust system or a cooling unit (required for some lasers) also directly affects power consumption. Trotec’s energy-saving function, which regulates the laser as well as the exhaust system in order to save power, also helps here.
A specific example for the power consumption of a laser
One laser corresponds to the consumption of 2 office PCs.
In order to give you a specific figure for power consumption, we have drafted the following example:
- A Speedy 400 laser machine with 80 watts laser power
- An average effective working time of 2 hours a day
- Of which 50% of the time with maximum laser power (80 watts) and 50% of the time with half laser power (40 watts)
This results in a power consumption of approx. 50 kWh per month, which corresponds to the consumption of 2 office PCs. This is always a surprisingly low value for many customers.
