The Multi Functional Electric Storage unit or MFE is the third tier of energy storage devices in IndustrialCraft2 (was previously 2nd tier but CESU got added as a 2nd tier). One MFE is capable of storing 600,000 EU, the equivalent of 15 BatBoxes.
INPUT: Accepts up to 128 EU/packet (Medium Voltage) into any of its 5 input faces, with unlimited EU/tick. If supplied with High Voltage or greater, the MFE will explode. The MFE will not explode if it reaches full capacity.
OUTPUT: Emits 128 EU/packet (Medium Voltage) from its output face (the face with the dot), with a max of 128 EU/tick. This current will destroy all first tier machines and Copper Cable if it is not first transformed with an LV Transformer. At least a Gold Cable is required to carry the output of an MFE directly. Ultra-Low-Current Cable and Copper Cable will burn.
The MFE can also accept a Redstone input. This will change the action of the MFE depending on which setting is selected. This setting can be changed by clicking the button with an image of Redstone on the top right of its GUI.
If you place Redstone in the bottom slot of the MFE, it will be burned and added to its internal energy storage.
