Power Requirement
Determine consumption: To keep track of costs.Our lab determines power requirements in stand-by mode and in disconnected state.
Even if you press the off-switch, some MFCs still consume electric current. The table below specifies the consumption in watt. The usage of current is calculated for one year, the price of one kilowatt-hour beeing 19 Cent.
If you want to determine the energy consumption of your equipment (printer, PC, monitor, TV, etc.) yourself and do not want to buy a good checking device you can lend one here
