How to use transformers
They change the voltage of energy packets, to connect machines of one tier to sources of another.
| Transformer | High side | Low side |
|---|---|---|
 LV Transformer | MV (128 EU) | LV (32 EU) |
 MV Transformer | HV (512 EU) | MV (128 EU) |
 HV Transformer | EV (2,048 EU) | HV (512 EU) |
 EV Transformer | IV (8,192 EU) | EV (2,048 EU) |
- The side with 5 dots is the high-voltage side; the other 5 are low. The wrench picks which side is high.
- Without redstone it steps down: big packets go in through the high side and small ones come out the others.
- With a redstone signal it steps up: small packets go in and big ones come out the high side.
Example
An 
MFE outputs HV packets (512 EU). To power a 
Macerator (LV) without it exploding: MFE → MV Transformer (down to MV) → LV Transformer (down to LV) → macerator.
Another option is a 
Transformer Upgrade in the machine: each one lets it take one more tier.
